Hi,
I were in your shoes. This what I've done.
Quant to increase from 44-49:
1. Get
Manhattan books, read chapter by chapter. Understand the basics. After each chapter attempt to solve problems in official guide and then here on this forum. You will easily find many problems on specific topic. Try to solve the problems without time constraits first and then under time conditions. While solving you need to have following accuracy: 500-600-100% accuracy, 600-700- 80-100%, 700-above 70%.
If you do make mistakes while solving, try to understand why did you make the mistake.
Usualy mistakes fall under:
1. Careless calculation mistakes
2. Lack of knowledge
3. Lack of time
Analyze and work on your weaknesses.
Verbal- even though I didn't get great score (34) but I know how to improve it:
SC - mahattan books must do- try not skim through them, but read chapter by chapter and understand EACH concept. After each chapter solve the problems. I would recommend when reading SC, to understand the meaning of the sentence. If you make mistake, try to analyze why all the answers but one is wrong. You have to 100% clear why those answers are wrong.
CR- here you just need practice-practice. But also there are some great books such as Holy Grail for CR. I don't remember the name but you can find tons of references on this forum
Reading- the same here is just lots of practice.
Usually it takes 100 hours of very diligent study to improve score by 100 points. But in your case it could be more or less, it all depends on how efficiently you are preparing.
Good luck!!
