from Q34 to Q48

I have started to prepare for the gmat 3-4 months ago. I used during preparation e-gmat verb and GMAT Club Test for Quant part. Initially when I attempted several CATs on GMAT Club Test, I was scoring about Q30-34 and I was pretty upset since I was naturally good in math in high school (14 years ago graduated). However, I decided to review the basics and then start attempting one-by-one. GMAT Club CATs not only gave me a sense of where and how I am performing, but also a sense of timing, which is very important during the real exam. After 3 months of preparation and usage of CATs, I have started scoring Q49-51 on the CATs and only have required polishing some small beats-and-pieces. So, when the real exam came, I scored Q48, which I am not satisfies and hence decided to re-atempt. During my preparation, I am only using GMAT Club Test for the math portion, especially as I took a real exam, because I believe it is simply the best tool available to score high. The task are very similar and very close to the real GMAT. Explanations are full. Performance analysis is very helpful as it shows you where is you weakest parts. I would definitely recommend to go for it to anyone who is seriously considering to score high on Quant.
