Generalised PREP CET Discussions

[RonakVasa]

I have found that Now as we have shifted from Prep Cet #3 to #4 we are facing a problem that we need to start a new thread for it . Thus, i have started this Generalised thread wherein we can discuss on the Questions, Answers , Difficulty Level, Attempts, Expected & Actual scores. Basically we can discuss the In and Out of Prep CETs 2007

I feel this naming convention of the thread will help discuss further...

Well for now we will start posting from Prep CET 4

So guys How was it ? wat is the No of attempts and how was the difficulty level according to u ?

Start Posting

[GirishRao]

Hi Ronak,

Prep Cet 4 was a little diffcult and lengthy compared to d previous ones.
I managed to attempt 140 questions and score comes to around 117. What abt u?? guys, lets have some more responses pls...

[ShashankShetty]

yup.... manged to attempt around 120.... score around 110!!

[ShashankShetty]

Ronak apna reviwe aur score toh bol!

[RonakVasa]

Definetly Shashank ......

I wud like to keep posting if u ppl do support ....

Well for Prep CET 4

Paper was a bit different , Can say a bit difficult but still i m not sure abt the difficulty .....

It missed the Forceful Argument , Assumptiions wala Section entirely

The Reading Comprehension , especially the 5Q set was completely bouncer for me !:confused: :confused:

The Visuals that i attempted got me confused a lot .....

Over all best score (topper ka not mine) should come around 145-150

I was too skeptical abt the answers that i got wrong.... i have a lot of doubts with it

I will start posting the doubts from tomorrow coz its too late for my brain to actually work !! he he he he ........

well yahan par kitne achivers wale hai ?

[RushabhsenSanghani]

Prep CET 4 was a good one for me .... Juzz 5Q on Syllogisms !!! probably that makes me score more. Neways,
Genuine Attempt 165
Score 141

[AnujDalal]

mine wer 150 attempts...score 138.

but guys correct me if i m rong but i feel the prep cets DO NOT have the required level of difficulty..

wats yr opinion?????

[RonakVasa]

anuj u mean u got a 98 % accuracy ?

138 / 150 = 98% accuracy :eek: :eek: :eek:
u r a computer buddy !!!!!!!

[AnujDalal]

nahi boss..
i had 150 serious attempts n 50 matka..

[RushabhsenSanghani]

well Anuj,
about the difficulty level , i wud juzz say that these are the same papers as last yr. and we do have statistics to show that ppl score more in actual CET.
I myself took CET last year so i can say that it is almost the same. Besides wat matters again is your %ile , so if the actual CET is tougher or simpler , Your %ile will be more or less unaffected. BTW, 2005 CET was much tougher.
Anyways looking at your accuracy , you already are doing an excellent job.
Ronak,
138/150 = 92% accuracy

Oh sorry i just got overwhelmed by tht number tht i did tht error ......or now i understnd y i get a less score in Prep CETs :confused:

[RonakVasa]

I found problem with the following Qs and its solutions as given by Peak Seekers :----- >

Q 17 :
Explanation Says that M has to either be >P or less than or equal to P
But actually it can be anything > < or = to P
So the option shud come as 4 but i dont know y they have said 3 !

Q 31 :
I feel instead of doing how they have explained , it is much better to just substitute the option values ....makes it faster and less amt of time to think

Q 40 :
as a^10 = 3^10 => a=3 or a=-3
as b^12 = 5^12 => b=5 or b=-5

therefore We cannot deduce a perfect relationship

Q 46 It was a good one ...initially it did not strike me so i did a fluk and got it wrong

Q 51-55 Complete Bouncer along with the passage

Q 62 They say tht "She said that yesterday.." creates an ambiguity abt whether she told it yesterday or she told yesterday she forgotto...
But according to me If she wud have told it yesterday than the sentence formation will look like this : "she told yesterday that... " so the ambiguity doesnt actually exists
Option 3 is definetly Right but i feel has some redundant data [i may be wrong]

[ShashankShetty]

i find the 113 question ambiguou.....

Last year he told his friend that __________________ bad manners

the correct ans acc to the solutions sheet is "he hated her for her"

its not clear whether 'her' refers to the frnd he is talking or someone else!

thats wat i feel.

[AnupamGadekar]

hi guys,
gav the ppr today coz hd tiss on tht day..........found the ppr a bit tuffer thn last time...
RC- found it tuff , even mesd up in vocab based rc
Sylogsm- whr were they saw jus 1 set, eithr ppr mein nahi tha or i skippd som pages dunno
Quant - pretty manageable but found it tuffer thn last time
Visuals - masterin visuals is a mirage for me..........found thm vry confusing

OVERALL I THINK THIS PPR WS A BIT TUUFER THN LAST TIME, BUT I THINK EASIER THN CET 2005

ON CET'S LEVEL OF DIFF I WUD GIV IT.....3/5
WHT SAY GUYS.........CM UP WITH UR SCALES

[i may be wrong]

I have an explanation for this.

yes you say M>p or M=p or M<p.

statement 1 says M>p
staement 2 says M <= p which means either M=p or M<p

if you consider both the staements together it would benothing but
M>p or M=p or M<p. hence

Option 3 is right as it says either.

Q 31 :

Q[i may be wrong]


They have given an exaplanation which is based on the fundamentals.
Although you get answer by substituting the values, But be carefull as there is a chance that substitution may not give you corect answer everytime.

[virendra]

Q 40 :
as a^10 = 3^10 => a=3 or a=-3
as b^12 = 5^12 => b=5 or b=-5

therefore We cannot deduce a perfect relationship

[i may be wrong]


you may be correct because you are trying to form a quadratic equation which does not have a unique solution.
what about this.

a^5 = square root of 3^5
then a=?

[virendra]

No, it does not create any ambiguity. It is clear that she did not water plant yesterday.

as per the rule for transformation in to indirect speech.
inverted commas are replaced by that, First person changes to third person, so i becomes she in this case. Past tense gets changed to past perfect, in this case it is done so in option 3, and finally yesterday should change to previous day, but it was there in any option, so not to worry about it.

hence option 3 is correct.

[virendra]

here you need to choose the best answer so the best answer was option 3, "he hated her for her".

[RushabhsenSanghani]

i wud totally agree with Ronak in case of Q40.
a^(even power) = 3^(even power)
so a = +3
coz (-3)^(even power) = 3^(even power)
same explaination for b = +5
that ways, according to me , answer should be 5 (Cannot be determined)

Guys, how about Q107
consider conclusion (i)
Orange juice is non-alcoholic does not necessarily mean that it is not a drink.
so, according to me, none of the three conclusions follow.
wat say ?

[RonakVasa]

I have an explanation for this.

yes you say M>p or M=p or M<p.

statement 1 says M>p
staement 2 says M <= p which means either M=p or M<p

if you consider both the staements together it would benothing but
M>p or M=p or M<p. hence

Option 3 is right as it says either.

No its not the case when u say M<=p means always m has a value less than the value of P including its value

But if M=P it has only one Value .....so there is definetly mistake in ur Solutions .....

If ur options are M=p and M<=p does that mean same ..... ????

[RonakVasa]

you may be correct because you are trying to form a quadratic equation which does not have a unique solution.
what about this.

a^5 = square root of 3^5
then a=?

Dont consider Quadratic or anything ......

if a^10 = 3^10 then it simple tht a^5 = 3^5 and thus a= + 3

Hence there is no scope of argument ...i discussed it with Nikunj Sir .... he too agreed to it

[virendra]

No its not the case when u say M<=p means always m has a value less than the value of P including its value

But if M=P it has only one Value .....so there is definetly mistake in ur Solutions .....

If ur options are M=p and M<=p does that mean same ..... ????


M<=p ( i cant write it in symbol form because of html constrain) M is less than P or equals to P.
M>P means M is greater than P

If you see both of them together you can see all the cases M=p, M>p, M<p.

if you cant get it, meet me when you come for the class will explain you.

Yeah Rushabh i had a doubt abt tht too but as i dint get time to post i cudnt do it ..... Definetly i see a lot mistakes in solution .....

but guess wat ? .... if this happens in CET thn we cant even argue .... :mad: :mad: :(

[virendra]

ok, then tell me what is value of (x) in these cases.

x^2 = 81

and x = square root of 81.

[RonakVasa]

ok, then tell me what is value of (x) in these cases.

x^2 = 81

and x = square root of 81.


Consider this (-9)^2 = 81

also (+9)^2 = 81

Hence x takes both Values

[virendra]

Yeah Rushabh i had a doubt abt tht too but as i dint get time to post i cudnt do it ..... Definetly i see a lot mistakes in solution .....

but guess wat ? .... if this happens in CET thn we cant even argue .... :mad: :mad: :(


here I agree because they have just considered a possibility as conclusion, it is not quite certain.

[RushabhsenSanghani]

both cases x= +9

[virendra]

both cases x= +9


Sorry, you got it wrong,

In first case it is +9 because a quadratic eqn. will be formed,
but in the second case it is only 9.

[RushabhsenSanghani]

exactly,
i wud agree to the solution had the set of arguments been
All drinks are alcoholic. Alcoholic drinks are harmful. Orange juice is non-alcoholic.

here, i can definitely conclude that Orange juice is not a drink ....

[RushabhsenSanghani]

but in the second case it is only 9.


virendra ,
well i checked this in wikipedia (reliable source for me) .... and yes you are correct. For others, heres the link:
http://en.wikipedia.org/wiki/Square_root

"Contrary to popular belief ........"

according to that
if x= sqrt (a^2)
then x=|a|
ie. value of x is always positive.

that ways , as you said,
if x=sqrt(81)
that means x=9
to make it more clear,
sqrt{(-9)^2} = 9 ..... Maths is funny !!!

So yes, you score......

But again, in case of Q40, this doesnt apply.
So still, my answer is 5 ie. Cannot be determined

I think now it has reached to a stage where roleof faculty is very critical. we should bring a faculty in this matter, so please ask your faculty to solve this i will tell my faculty to post the answer.

Hi rushabh ---

u may be wrong here

sqrt{(-9)^2} != 9
sqrt{(-9)^2} = (-9)^ (2/2) = (-9)^1 = (-9) :p

Its only according to the textbooks or computer programs tht sqrt{(-9)^2}= 9
Bcoz by dfault it is tht positive values are to be considered .....

but if u r finding possibilities in an experimental case thn u have to consider both values ....which is the case for data sufficiency

Wat say Faculties ? and Viru Sir get in Nikunj sir .... make for him compulsory to be here twice a day atleast to solve these doubts !

Square root
From Wikipedia, the free encyclopedia
Jump to: navigation, search
In mathematics, a square root of a number x is a number whose square (the result of multiplying the number by itself) is x. Every non-negative real number x has a unique non-negative square root, called the principal square root and denoted . For example, the principal square root of 9 is 3 (denoted ) because . The other square root of 9 (not the principal square root) is −3.
See means sqrt(81) = +9 ....Hence Proved

:) :) Fundamentals Clear :) :)

[RonakVasa]

136 in PREP CET 4

Yaar Mods pls get us our Question - to - question information so tht we know wat questions we have got wrong to analyse !

pls pls pls get this !

if you read little further in that link . in Properties look for the point that starts with "Contrary to popular belief ......"
According to that,
when x < 0, sqrt(x^2) is positive by definition, and thus sqrt(x^2)= -x.

so lets take a value < 0, say -9
so, sqrt(-9^2)=-(-9) = 9

[AnujDalal]

send in yr scores ppl.
mine is 137..
i feel we shud hv the scores of top 100 rankers.wat do u feel ppl???

[virendra]

Hi rushabh ---



Wat say Faculties ? and Viru Sir get in Nikunj sir .... make for him compulsory to be here twice a day atleast to solve these doubts !



surely. I will try to do this.

[ShashankShetty]

hi guys.... kya hua.... post karo kaise gaya prep5????

[RonakVasa]

Dont ask ....was not in a good mood or say health to give prep 5 ....so m nt expecting much from it .....

hope i dont go to low

[ShashankShetty]

i suppose it was a bit difficult......

[PunitSaraf]

hi sashank , i dont think prep cet 5 was too difficult , it was just bcoz prep cet -4 had no syllogisms and visual reasoning was also easy in it , whereas in prep cet -5 syllogismss came for 15 marks and also visual reasoning was bit difficult.Neways i managed to score only 115 ;(

[ShashankShetty]

okie.... my score is around 105..... are these papers easier than the actual CET??

[AnupamGadekar]

hii guys, my review of prep 5

1) tuffer thn prep 4
2) dificulty level mein exactly same to cet 2006
3) visuals tuff , me sweatin
4) jumbled para made me go nuts
5) RC ws horrorible
6) good to c dificulty level going up
7) i gues evry1's scores mus hv droppd
6) found 4 errata, at least i think so

[AnupamGadekar]

shashank i think prep 1 to prep 4 were on the easier side......but prep 5 ws equal to cet 2006........i cn def say tht....

[AnupamGadekar]

RONAK ITS OK...........ACTUALLY EVEN ME FEELIN A BIT LOW TODAY........BUT GUESS WE HV NO OPTION THN TO FGHT IT OUT......JB'S A DREAM FOR EVRY1......TC OF UR HEALTH.

[ShashankShetty]

difficulty level same as 2006!!!!! i heard 2006 was the easiest of all the years..... even according the analysis sent to us, CET 2006 ka scores were much much higher than the average score of the students taking the exams!!

[ShashankShetty]

what happened??? no one posting these days?? everyone studying very hard kya??

[RonakVasa]

arey nahi re i havent yet analysed it completely so am not able to put in my queries and guess wat .....we hav a exam tomorrow so ppl acquisitions strts for the new test !

[RonakVasa]

ONLY MANAGED 116 :( :(

[AnujDalal]

any ideas wats the highest score?????

[ShashankShetty]

yup, highest is 131!!

[AnupamGadekar]

my review of prep cet 6......

1) i think a bit , jus a bit easy tht prep 5........but matchd wid cet level
2) rc ws too simple, although did a few mistakes
3) visuals meduinm to simple
4) jumbled para ws a relif as comprd 2 last time
5) found the footbal set n the 7 towns ABCDEFG with males n female ratio v tuff

my genuine attempts 157 + 43 tukkas
gettin 135
i think error in Q)6 and a time n wrk prob

cheers

[RonakVasa]

I m Having a down time it seems ....Prep 5 got me just 116 and Prep CET 6 was even worse ....

may be PREP CET 6 was a cause of Paper after heavy loaded work ....but excuses apart ......

I dont know was not able to attempt more and mistakes where lot ! ..... so am just standng at 100 :( ...... m i getting better or worst


Will try to tighten the rope for Prep 7 ..... Fingers crossed

[ShashankShetty]

dude, check whether there is an increase or decrease in your percentile not the absolute score.... if ur percentile isd increasing it means u doing well, one more question, do u guys attempt visuals?? i mean where is the time? how do u'll manage it?

[RonakVasa]

Na the percentile itself isnt increasing .....!!! :(


It got decreased ...... i know its not the score but according to the paper u can guess wat is a good score

[ShashankShetty]

ur graph will always be parabolic, dont worry.... achcha tell me do manage to attempt visuals?

[AnupamGadekar]

RONAK BELEIVE ME GIVING A 2.5 HR CET AFTR WRKING CN MAKE A HELLUVA DIFFRNCE..........ME NT SAYIN THIS JUS TO PLEASE U.......NX TIME TRY GIVIN TEST WHN U FRESH......TC

[RonakVasa]

Yaar but Wed CET i need to give it the day end after work only and is a big issue i was afraid of from the start .....


but still i need to perform in any circumstances now or else i m screwed .....

coz we dont know wat may happen in the main CET day !!!!

[AnupamGadekar]

yaa.......u cant help bout the wed test........but nw see the sunday test...i m sure thr ll be + ve differnce.........any othr mock u gav???

[RonakVasa]

ya plnning to give CF 1 today ...time hi nahi milta yaar weekdays main ..... today there is an event in office so i can leave early ...... to try karunga

hehe! good 1 ronak...........scores hv begun sliding down......i think last 3 pprs were decent in diff........but still.scores nt upto mrk.......am a bit confusd whtr i shud go for mor pprs or practice more

[AnupamGadekar]

guys pls suggest any strategies for last 15 days...............wht to do??? wht nt to do?? which mocks to solve which nt to???

[RonakVasa]

My score is

Going down down down .... down down
Meter down down down ..... down down

Y cant score be consistent enough

wats the top score in Prep 9 ?

[RonakVasa]

guys pls suggest any strategies for last 15 days...............wht to do??? wht nt to do?? which mocks to solve which nt to???

Wat anupam ..... u shud be giving us techniques and tips ..... wat r u asking for ?
