I want to add something important: if all you're doing is doing problems from the OGs and GMATPrep question banks at random, then you're not building any particular content knowledge in a systematic way.
Here's how you should be studying:
1) Read about the underlying concepts and strategies in content-specific strategy guides. I of course think Manhattan Prep's are excellent, but any company's guides will give you a grounding in the concepts taught.
2) Do a set of OG problems that relate specifically to that topic. Mprep has a tool call Navigator that will allow to you search for OG problems by topic and track all of your data on accuracy and timing:

3) Review your answers thoroughly and track any mistakes in an Error Log.
4) After you've studied a good deal of content, then do random sets in the OGs to practice pattern recognition and timing.
5) Do a practice test every 2 weeks to track your progress.
6) For any topics that are weak on the practice test, go back and do another set of practice problems specific to that topic.
If you're looking for additional resources to practice after you've studied topic-by-topic, Mprep offers Question Banks, Practice Tests, Challenge Problems, Workshops, and more. See here:

[email protected] if you have any other questions about our resources.
But whatever resources you use, make sure you use them strategically by studying topic-by-topic first!
