I've been studying for 3 months now using the Manhattan GMAT
and OG 13
books. I think I'm OK on verbal being a native speaker. However I'm really struggling with the maths. I'm really not used to the American format tricky type questions. I have a fairly strong academic background, but have been out of it for 5 years.
In my last test on Manhattan I got a 40 for quant. Getting tired towards the end probably didn't help. I got the last three questions wrong which reduced my percentile 10%. That said, I really need to do much better if I were to aim for around a 700.
My strategy so far:
Going through each Manhattan GMAT
book one at a time, doing the questions at the end of each chapter and doing the OG13 questions.
I had been planning to take the test in mid October.
What do I do next? How do I best prepare?
