I've just come out of my own harrowing experience (Oct 6) fairly unscathed, and thought I'll give some tips to those who are panicking over GMAT prep... you WILL survive!
My own story - I'd started looking at the Official Guide (OG) casually in mid-September, and began cramming for real, for 2 weeks straight Sept 21 - Oct 6. My advice is that it's better to just go for gold, and be tight and focused on your preparation process. The adrenaline on the day also really helped drive it home for me i.e. I absolutely gotta ace the thing on the first try.
A few tips:
1) Resources / timing allocation
(a) OG11.
- The Bible! A useful tip (which I was not aware of until 2 days before my own GMAT ordeal) is that the most difficult questions for each section seem to be parked at the back.
- E.g. there're ~200 Critical Reasoning questions - if you're finding the first 50 too easy, skip right to say, Q 170 onwards.
- I was getting almost all the earlier questions right on the OG (but messing up my GMATPrep (which of course is adaptive), so was feeling frustrated as to why I was finding OG boringly easy, but GMATPrep incredibly challenging.)
- Turns out that once I skipped to ~Q170 onwards, I got a fair number wrong, then scrupulously pored over the explanations at the back of the book.
- Really improved that way once you review your work.
- In fact, I only did about 60 questions for each section (PS, DS, CR, SC, RC) out of the entire OG, cos I simply didn't have time to finish the 1,000+ questions in the OG.
- I am not suggesting you cherrypick this way if you've LOADS of time, but personally I studied for 2 weeks intensive cos I'm trying to get into Round 1 (and only decided in September 2008 that I wanted to apply for 2009).
(b) GMATPrep.
- You get 2 free when you sign up for your test date. Use them well. I actually fired up the 2nd Practice Test twice and found that you can do it again (although there are some repeats).
- Apparently this is pretty accurate. It certainly was the case for me.
- The upside is also that GMATPrep's layout (colours, format) completely resembles what you'll be getting on test day, so it's sort of nice to familiarise yourself.
(c) Manhattan Forum Search.
- Awesome and very under-rated tool.
- In my own experience, I found it CRUCIAL to review my answers after every test. Test taking is all well and good, but you gotta learn from the questions, cos GMAC repeats concepts and "types" of questions, even if they don't repeat the exact question (duh).
- Given that GMATPrep, unlike the OG, does NOT give you explanations behind the answers, I'd spend up to 3 hours searching MGMAT's forums after every GMATPrep test I took, to make sure that I understood the concepts behind the questions I'd just tackled.
- I also found it v useful to keep a word doc list of all the "lessons" I'd learned.
- E.g., I never knew until GMAT preparation that any length of a triangle had to be shorter than the sum of the other two sides. Or that "like" is used as a comparison whereas "such as" is used to list examples in the GMAT world.
- MGMAT's forum is insanely helpful - there are all sorts of tips and real OG and GMATPrep questions posted, and the answers come with explanations from the instructors.
- Beyond that, they have great short lessons to bring you up to speed on certain concepts. E.g.: http://www.manhattangmat.com/strategy-series-probability.cfm - just one example out of many helpful guides.
- I must've spent more time on MGMAT's forum than I did practising questions on the OG, and I consider it time extremely well-spent. (Thank you MGMAT! How can I give a paypal donation or set up an altar of appreciation?)
(d) Prep Programs.
- I did not pay for any lessons with any of the Prep programs. I'm sure they are useful, although as mentioned, my problem was lack of time.
2) How much prep / how many tests should I do? What are typical scores?
- I reviewed the Math concepts in the OG, and then did about 60 practice questions from each section of the OG (i.e. ~300 for all 5 sections)
- After I was more comfy with the concepts, I did 5 prep tests (3 GMATPrep (one repeat), 1 MGMAT, 1 Kaplan)
- Kaplan's practice test is pretty lousy IMO - it didn't seem adaptative and the Math was way too easy. Also not sure how their scoring works, because although I got all but 2 questions right on their Quant section, they scored me at 44 for Quant (?!)
- In hindsight, you don't need to do that many tests. I think 1 MGMAT and 2 GMATPrep are more than enough.
- Otherwise, my scores were all over place:
MGMAT: 640 (Sept 21), 43Q, 34V. [I was REALLY depressed when I first saw my score. My advice is that MGMAT is harder than GMATPrep, so do NOT be discouraged if you see low scores.]
GMATPrep (End Sept and Early Oct): 710, 710 [Forgot the V/Q allocation]
Kaplan (Oct 4): 680 [Forgot the V/Q allocation]
GMATPrep (day before my test, Oct 5): 760 (but I suspect it was this high cos there were repeat questions) [V46, Q51]
3) Recognise your strengths/weaknesses and work on them
- My weakness was Data Suff - I hated the thing, so I spent more time focusing on it. MGMAT's AD/BCE and BD/ACE elimination strategy is very useful (more info elsewhere in this forum, so I won't repeat it).
- Otherwise, improving on your weaknesses is all well and good, but IMO it's equally useful to play to your strengths.
- I knew verbal was my strength, so I focused on making sure I really aced verbal (brushing up basic grammar, combing through MGMAT's forum, learning about GMAC's take on what they perceive as "correct American English" - it's not always intuitive).
4) Pace yourself!
- Speed is of the essence
- I used a simple grid where I gave myself 20 min per 10 Quant questions, and 18 min per 10 Verbal questions.
- On Test day itself, I scribbled at the top of my pad (for each section):
For Quant:
1 75 (min)
11 55
21 35
31 15
For Verbal:
1 75 (min)
11 57
21 39
31 21
41 3
- In other words, by the time I got to say, Q11 for Quant, I should AT LEAST HAVE 55 min left in the ticking timing on the screen. Etc.
- You can have a much more refined grid than that, but I didn't want to keep checking the ticking clock, so I found that tracking my pace using blocks of questions of 10 worked very well for me. Find what works for you!
5) Test Date
- Important to keep energy up.
- I put some jelly beans and granola bars in my bag and munched during the breaks. Also had some tomato juice (but I spose Gatorade or other would work just as well)
- Stretch during the breaks.
OK, hope the advice is somewhat helpful... and good luck, everyone!
