1. If you want to improve your timing, you have to practice with a timer. When you practice untimed problems, you're not really doing the same thing that you'll have to do on test day. Solving a problem with no timer is
very different from doing it with a timer - you'll be using different strategies and worrying about different things. If it's overwhelming to do a whole timed set, start with just two problems at a time. For instance - take two SC problems, set a timer for 3:00 (that's a little generous, but it's okay to start with) and answer them both within the time limit. You don't have to get them right; you just have to at least make a reasonable guess! Then, as you get comfortable with the exercise, move towards doing five, ten, or twenty problems in a row. Don't worry about 90% accuracy - shoot for 60% accuracy, since that's about where you'll be at 'your level' according to the GMAT.
2. Some question type specifics:
- On SC, are you finding splits, or are you reading the answer choices through one by one?
- How are you with modifiers and parallelism? These are two issues you can study that might make you faster at SC.
- Do you have flashcards for common grammar rules and 'triggers' (i.e. 'when I see the word WHICH, I should start thinking about this')?
- On CR, are you keeping a problem log and trying to identify common argument / wrong answer / right answer patterns as you review problems? Here are some examples of what I mean by argument patterns:

Are you actually reading just for structure, or are you falling into the trap of 'reading every word, but trying to make your eyes move faster'? Fast RC readers don't do it by just reading the words more quickly. They're actually reading
less of the passage than the rest of us.
