Try taking initial diagnostic test. From there you assess where you stand.
Jot down your weaknesses and work on it.
In my view:
- SC you can use Manhattan SC and SC grail
- CR powerscore CR Bible
- RC, try practicing more questions and learn different types of questions.( you can find different strategy in this forum).
- For problem solving try to learn concepts first from manhattan strategy guide. Then try solving advances problem from this forum.
- For data sufficiency too, you can use manhattan strategy guide.
- Try solving OG problems once you complete each topic, let it be SC, CR or PS.
- Give some time to yourself to learn new IR section and finally AWA(you have many kinds of template. You can find these templates in this forum).
- Once you complete with concepts try taking any of the CAT test(gmatprep- can be downloaded from official site or you get 6 CAT test along with Manhattan strategy guide which is good).
NOTE: OG is a must.I hope this would help. For more help please don't hesitate to post.
