Extreme Challenge Set - Jeff Sackmann

So after completing Jeff Sackmann's Total GMAT Math, I moved on to Extreme Challenge Set.
If you have read reviews by other users you will know by now that the Extreme Challenge Set is very heavily oriented towards Probability & combinations.
I believe, Total GMAT Math and the EC set compliment each other very well. TGM focuses on each topic individually and then the EC set puts it all together to give you 700+ level questions.

So the EC set is split into 2 sections -
1) Problem Solving - questions 1 to 65
2) Data Sufficiency - questions 66 to 100.

I attempted to solve all the questions in under 2 mins. Before I started working on the questions, I split the PS and DS sections into 2 parts each:
PS: (1-35) & (36-65)
DS: (66-80) & (81-100)

I first solved PS (1-35). About 7 of them were based on Combinations + some other section. About 13 of them were based on Probability + some other section. A few geometry question and a sprinkle of number properties questions. Obviously I cannot classify each question into 1 or 2 exact categories. In the 700+ level questions, categories melt into each other.

    Questions: 35
    Wrong: 12 (4 careless, 7 tough, 1 Knowledge gap)
    Accuracy: 66%

Then i picked up DS (66-80). Few inequalities, few NP's, a few coordinate geometry based questions and of course probability and combinations.

    Questions: 15
    Wrong: 6 (3 careless, 3 tough)
    Accuracy: 60%
_______________________________________________

After reviewing all the questions (right and wrong), I went back to TGM, pulled up the Probability & Combination questions and tried solving them. They seemed so much more simpler now. Hah. :)
_______________________________________________

Yesterday night I picked up PS (36-65). Many of the questions are based on the concepts learnt in the first half.

    Questions: 30
    Wrong: 8 (4 careless, 3 tough, 1 not sure)
    Accuracy: 73%

Today morning I picked up the remaining DS (81-100) questions.

    Questions: 20
    Wrong: 4 (1 careless, 2 tough, 1 not sure)
    Accuracy: 80%

Overall result:
So overall, I solved 100 questions (all timed) and got 30 questions wrong (15 - tough, 12 - careless, 2 - not sure, 1 knowledge gap).
Final result: 70%.

I am not too happy. I wanted to score in the 80- 85% range. And I could have easily done that by cutting down on my careless errors. 3 to 4 of them as stupid as me marking the wrong answer after solving it exactly right!! I deserve a special title just for this! What I am happy about is that my accuracy increased in the 2nd half as a result of what I learned in the 1st half. I am also much more confident solving Probability and combinations questions. Working through this set has boosted my overall confidence and I think it was definitely worth $25.

I Just did 45 Question in Extreme challenged in 95 mints
39 are right , 4 are probability questions:( .. this set is too heavily skewed towards probability..

How representative are these questions of the real gmat math?

39 out of 45 is very good!
When you move towards the 700 - 750 level questions, there are more probability/permutations/combination questions that appear.
I personally feel that working on this set of 100 questions is worth it just to get that 1 prob/permu./comb. question right at the 700 - 750 level. From all the questions I have been solving, I can say for sure that the quality of this set is right there at the top of the pack. I think Jeff Sackmann does a very good job of creating GMAT like questions. What has been your impression of the quality of the questions? And did you want it to be tougher? Have you been working on the GMAT Club tests?

I think the questions are good level but little too many prob/comb ...
Im currently working on MGMAT Adv GMAT Quants and really like them...
I'm happy with my accuracy though ... will start club tests next week.

Wow. So I totally bombed my first Knewton GMAT Practice test. I score a 660 (Q40, V43). I have never score so low on the math section before. :| Dammit, I knew I shouldn't have started the test at 9 in the night. I was so tired from the really long day at work. All my mistakes in the math section were careless ones. Bloody 'el.

25 June 2011

Kaplan CAT#1 - I just took my first Kaplan CAT from the CD and I scored 610 (Q50, V30).

First impression - Verbal is very distorted. I did not like it at all. And I only scored a V30. I did not think I would score that low! :|
Quant - I have heard that Kaplan quant is relatively easier than the quant in other CAT's. So I am happy I scored Q50. Although I would have liked a Q51. :)

GMAT score estimator tool says that I should be at a 690 level on the real GMAT. Still not enough. I need more!!

30 more days.

4 July 2011

GMAT Prep 1
So I finally sat down and took the GMAT Prep 1 exam.
I scored a 700 (Q48, V38).

I still need to review all my wrong answers, but it looks like I got 12 questions wrong in quant and 10 questions wrong in verbal. That's a lot of mistakes!!

I was hoping for a much stronger verbal score, somewhere around 42-ish. :|

Anyway with 21 more days left to go, I really hope to push this to the 730 - 750 range.

So on Sunday (17th June) I attempted GMAT Prep #2.

I scored 710 (Q48, V39).

I am feeling conflicted. Dammit. I was hoping to get a higher score in both quant and verbal. But at the same time 710 seems alright. I still have 1 more week to go. I am going to be focusing on GMAT Prep, OG, and knewton verbal. I cant wait to be done with the GMAT. So many things to do. So little time!!

7 more days.

No. I am not going to take up any MGMAT CAT's. CAT's I am using - GMAT Prep, Knewton (6 CATs) and 1 Kaplan CAT that I did not like at all. I am sticking to the basics and I am not doing any kind of super-hard-questions prep. I find that very demoralizing. I used the GMAT club tests a little bit and actually even liked them (really good quality). But then they are just way too tough and I doubt that such questions will ever show up till the Q50 level.

I am guessing that you are closely reviewing all your answers in GMAT Prep since it does not provide you with a good analysis report. good luck!

as far as i know MGMAT CATs are ideal prep for gmat. they are similar to the gmat algorithm but are a little tougher so that u dont slack. imo knewton CATs sucks. if you really want to practice, the gmatclubtests are the best for math.
a gmatprep score of 700 will probably get u a 650 on the actual thing as u might know,(think u are aiming for more than that) so my advise is, if you have access to MGMAT CAT use it.
i must warn you though that any sudden change in your method of prep may affect you adversely, esp. since u practically have just a week. so i advise u to take the test. if you get a good score u can rest ur mind else dont sweat abt it cos it wont matter much.After all confidence is the key
good luck

Where did you pull this piece of information from? The GMAT Prep is the best indicator and as long as you are not too volatile in your scores on other standardized test preps, you should be scoring somewhere around what you get on the GMAT Prep.

Well. Today was it. I just got back from the testing center.

GMAT #2 -

710 (Q48, V38)

While I am not ecstatic about my score, I am not disappointed either.
I will write out a more detailed debrief in a short while.

that is from the numerous experiences in this forum including mine, i got a 680 in gmatprep and 650 in the actual thing, also if you chk out the score calculator, it will show the ideal difference.
gmatprep is easier than the actual thing and it might hurt you if you expect the same score in actal gmat.
However there are exceptions, like u.
so all this aside, CONGRATS on a great score!!! :woohoo
