Grockit CAT 680 (q37, v41)

in my opinion verbal result is higher then my real because i was familiar with majority of questions, but i can not understand why i got so low result in math??
during CAT i did not drink any caffeine and felt lack of time in math as well as in verbal parts.
PS. after reviewing math part i see that result is so low because i did a lot of silly mistakes in first 10 questions, so CAT became to give me the hardest questions only in the second part of test. I should be more careful!

Cause for optimism

I make a progress in SC. I've just found a site www.gmatonlinetest.com and solving one SC quiz that contains 15 SC from it I did 14 out of 15 questions correctly. Seeing SC question I notice typical mistakes in wrong variants at once.

I do great progress in CR too. Tell the true I can make a mistake in CR question only if I do not understand argument or question. I do correctly ~70% of LSAT RC questions, but my performance in GMAT RC fare worse.

My main problem in math and in verbal part is lack of time. But I hope caffeine helps me do all test in time in upcoming exam. In real exam that I had in May due to caffeine finished math part 5 minutes before time ended.

my disease

10 days ago i caught an severe angina. i studied very little, because it is impossible to do something effectively with favor 39C. I've restored to health so will continue to solve GMAT questions. I'll have GMAT 14 of October. I am going to remember math in this week, begin to practice AWA and read a lot of RC passages, because RC is my weakest side...

as it uninteresting to write about tuition))))

Fluctuation of performance

It's my yesterday's result:

It's my today's result:

I don't know why, but in some days I feel that my IQ as high as Indian guy's, but in another days it is very low. But it is not bad, because just in "bad" days I come across new thought and new ideas.

So today I'll not study but will write essays.

BTG Practice Questions for people who want to gain 700+ not for beginners

I’ll get a free access to BTG practice questions, so write true review of them.

Questions
BTG practice questions are in average harder then those in OG or in Grockit and written in more challenging language. If almost all CR and SC questions from Grockit are modify ones from OG and their essence is just the same but changed name of companies, persons, branches of economy in witch companies engaged, etc, majority of BTG CR and SC questions resemble to those in OG not so strong. They more alike to Kaplan’s ones. Unlike those in OG some of BTG CR questions have math basis, and a lot of them test parallel logic as LSAT questions do.

So the fact that questions are difficult is good for applicants familiar with GMAT or with level higher than 600. But beginners (especially nonnative speaker) should in first solve easier questions, after that do harder ones. Stacey Koprince wrote there is a “layering” of DS questions but in my opinion such layering exists in questions of another types too, and by virtue of this fact the probability that person who solves easy questions excellent but doesn’t fully understand written English answer to hard question could be less than 20% so even very lucky person with real level 550 cannot get in real exam 700+. And practicing only hard questions can astray person in real exam during solving easy ones.

Compared to LSAT ones BTG reading comprehension passages are easy, but questions to them fare more difficult. But as for me this feature is inherent to RC sections from all sources. During lust several month I solved only LSAT RC passages and was unhappily surprised that question in GMAT harder.

Math questions from BTG like verbal ones in average are more difficult then those from OG. Math questions from all sources including OG and BTG as well as from real GMAT are very resemble to each other.

fiches of site:

advantages:
+ site creates log of mistakes automatically.
+ questions do not repeat,
+ you can see percentile of correct answers to every questions, so it’s possible to estimate their level of difficulty
+ excellent and concise explanation in written and video format
+ big quantity hard questions

drawbacks:
- you can not customize studying in great degree. You can choose among Verbal and Quatative, or among SC RC, CR, but you can not solve only geometry questions, or SC that test you knowledge of idiom. In addition you can not choose difficulty level of questions.
- inconvenient small window in which you can read RC passages
- the page with result works not clear, and renewed very slowly in my work's comp with Widows FireFox and broadband Internet and as well as in laptop with Ubuntu (Linux), browser FireFox and 3G Internet. (I am situated in Ukraine.). But it is not very severe problem.

Conclusions:
BTG practice questions answer are helpful for people who familiar with GMAT format and solve at least all questions from OG, or accomplished gmat course and find additional practice.

Wishes:
Add please to page with results column with date and time (as i drew) . As for me it’ll be good idea to add to site fiches that enable to analyse results, create graphics of improving results and so. Although these fiches will be especially useful when the number of practice questions will grow to 1000-1500 ones.

BTG Practice Questions

Several days ago CEO of Beat the GMAT David Park offered me free access to BTG practice questions. Thanks him for this! I am solving this questions now. It is excellent to have sufficient quantity of GMAT questions for preparation! But during several days i’ll do all of them so will be find another sources.

There is in picture my current result. Is it good or bad? Percent of right answers is not high, but questions in BTG are harder then those in OG

What is interesting, when i begun solving this questions result was very bed but now it improved.

Today or tomorrow i’ll write detailed review of this new product of BTG.
In addition i want to write that BTG lunched free B-School Essay workshops. I guess it will be useful not only for me but also for other applicants.
