I scored 157 on my first diagnostic 3 months ago (prep 25) (not totally cold because i did study a bit 2 years ago but decided to get a master first). I've spent 3 months, studying non-stop (no work, up to 50 hours a week some times). My score staying pretty much the same (with one pt a low 150s for prep 59 and highest 163). My LG improved a bit from -11 to -5 on average. My LR and RC are getting worse. I used to get -5 on RC, now is around -8 to -10. My LR used to be -10 to -12 at the beginning and now is like -20 to -23. I took the dec test today and ended up canceling the test, because of the RC and LG. I am going to spend 6 more months to prepare for the june 2015. People that I know have improved their score 5-10 points with full-time jobs. I don't get what went wrong with my study. I did a lot of drilling in the cambridge package for LR. But under time condition, the techniques I learnt for LR and RC often conflict with my instincts.
I still have preps 46-73 fresh (except 59, 72, 57, 62), about 24 prep tests. I used lots of other tests for individual sections. I have taken about 10 full-time practice tests so far. How should I utilize those tests in the next 6 months to maximize my score? What should I do to improve my LR and RC scores? I feel like I do have a potential to hit 170 but don't know where I actually went wrong. I studied the most for LR and LG for past months. If anyone experienced the same thing but managed to overcome that difficulty, I am happy if anyone can share their experience. I would appreciate.
