My recommendation to you would be to first figure out more specifically where you are weak. It looks like the data is telling you your weakness is RC. RC is a pretty broad topic, though. I would suggest looking through your CATs to figure out what exactly about RC is throwing you off. Is it the general questions? Tone? Inference? Specific detail questions?
It's important to get this more specific data before you try to target your weaknesses. Once you've determined where exactly you are weak, I would recommend reading through just the specific chapters or sections from the RC guides that relate to those areas (no sense reading through the main idea section if you're already a master of main idea!). You can use the time you saved by not studying your strengths to study other weaknesses within SC or CR. (Again: be specific. Are you weak on modifiers, idioms, pronouns, subject-verb agreement, etc.?)
Once you've done the reading for your weak areas, I'd focus on the quality of your practice questions, rather than the quantity. Reading, taking notes, and doing 3-4 RC questions should take you about 8 minutes. If you analyze your work properly, that should take you another 15-20. So if you set up a 2 hour study session, you're only looking at doing 5 or 6 full passages. Still, this is preferable to doing 60 questions in 2 hours and never really stopping to learn.
All that said: When you're two weeks out from the test date, it's probably time to stop acquiring new knowledge and start focusing on your game plan for test day. This means practicing your timing, knowing where you're going to guess, and generally deciding how you'll attack the test given your existing strengths and weaknesses.
Hope this helps!
