Thanks! Through keeping an
error log this time, I'm beginning to realize how much combinatrics and probability are for me. Do you know how much concentrated emphasis I should be placing on these topics? Or would just doing a bunch more practice problems in general be more beneficial?
Doing a bunch more practice problems in general won't help you.
Keeping an
error log is the first step to improving regardless of your current level (unless u're <500, then you probably need to work on everything).
probability questions are not super common on the GMAT and usually appear as harder questions from my experience. I believe I only had 1 on my test, and my quant score was slightly above average (compared to others on this forum). I wouldn't put too much emphasis on it unless u're shooting for 50/51.
What I would focus on is take the following steps (for both quant and verbal) -
1. Look through your
error log2. Find all the concepts you've missed questions on (I'm guessing there are quit a bit of other concepts you can focus on in both quant and verbal.)
3. Find a book (GMAT or not, but GMAT specific helps, i.e. the bibles) that goes over these concepts and review them
If you follow the above steps and cover all the concepts in quant, then all you have left to do is applying the concepts faster, since time will be your constraint - but by this point you should be scoring in the high 4x or 50/51.
For verbal - if you're weak in SC, this is the EASIEST to fix imo - learn the most common 7 or 11 grammar rules that the GMAT tests.
If you're weak in logical reasoning, use the bible and you'll ace this (I didn't use it but others have all said its great).
If you're weak in RC, this is a toughie and takes the most time to improve on imo. However, if you're shooting for something like a 40 on verbal you can risk being weaker on RC and just make sure you know your SC and LR.
again, error logs are pivotal to zone in on what concepts you need to learn/cover in more depth. Use it for both quant and verbal. Do as many problems form the
OG as needed to identify weak areas, do GMATprep many times to practice, and you'll be fine if you put in the time.
