Looks like you're progress has been similar to mine. I too started out with a
MGMAT CAT 1 570 Q36 V33 with no study. After about two months of regular study I'm up to 670 V45 Q36. I consider myself better in Verbal than Quant even though I have an engineering background. But I strongly believe that the key here is to do a bit of both, Verbal and Quant in order to keep both 'sides' of the brain active.
For quant, I would strongly reccommend the
GMAT Club tests. They're painful and hard. So far I've done 10 of them and they helped me in the following ways:
1. The tests really helped me solidify the concepts.
2. For some reason, I after doing the first 5 tests or so, I got much, much better at Inequalities and Odd/Even type problems
3. You learn some very useful tricks/ ways to do word problems more efficiently.
4. After I did these I actually found the
MGMAT Quant section easy (although I did have timing issues)
I would also recommend the Manhattan Challenge Sets in the
Gmat Club Test Section. They're not as hard as the
GMAT Club tests but still make for a great learning experience overall.
Some people say its better to focus on the concepts than do a ton of problems. For me, doing a ton of math problems worked out better (practice makes perfect!) You will have to figure this one out on your own.
Don't overdo the CATS; remember they are meant to:
1. Help you see shere you stand
2. Help you build stamina.
For instance I don't think the Princeton CATS are a good estimator of performance but they make for good stamina practice because you can go into it knowing that you're not focusing on the score but rather your endurance.
For SC, make your own flashcards for all the grammar rules that you learnt. This has been VERY helpful to me in improving my SC performance.
And lastly, I agree with you on
MGMAT Verbal; I found it super tough compared to the practice questions that I have attempted thus far. I feel the GMAT and Kaplan verbal is way easier.
Good luck!
