Since you were out of tough so I will suggest you to go through Number Properties first!
I will suggest you to through Manhattan theory guides.
Go through the books in order.
Once you are done with one chapter then practice the questions either from grockit.com or gmatclub questions(you can find the gmat club tag's ling in my singature)
Once you are confident with a chapter then move on the other one
something like this
For i=1 to end
-> Study "chapter i"
-> go to grockit.com and schedule game for "chapter i" with difficulty level easy, If doing good then increase the difficulty to "medium" else go to next step
-> re-read the "chapter i" if you are doing bad
-> else goto next chapter and repeat the above steps.
Please a progress chart. Something like this:
Prepare a xls sheet (topic by topic).. and keep a track of your progress on a daily basis. Use color coding (Red,Orange,Green).
Red: You are weak in theory - brush up your concepts.
Orange - Done with theory but weak in application of the concepts
Green - Done with the topic
Hope it helps!
