Need to improve my timings in CR. Any suggestions

Absolutely. Timed practice is essential. I recommend that you practice with strict timing, but then go back untimed and analyze your work. Before you check the answer, you should be able to explain why you made the choice you made, and why the other 4 choices are incorrect. If you turn out to be incorrect, you will need to recalibrate and figure out where you made a mistake in your reasoning.

By the way, some people find that they do best on CR if they allow themselves an extra 30 seconds or so as needed. If you want to experiment with going to 2:30 on some CR problems, you will just have to find that time in your overall "budget." On the other hand, you may find that extra time makes little difference to your accuracy, in which case you may want to stick to 2 minutes max.

Hello Dimtry,

These suggestions are helpful. Can you please suggest some similar suggestions for RC section?

Basically, everything above applies to RC above. The only difference is in how you adjust your timing. You may find that you have a particular topic area or passage type that takes you a little longer. If so, give yourself permission to read for a little longer up front. For instance, some students have a hard time with complicated science passages. If you take 5 minutes up front, rather than the usual 4 for a long passage, that only translates to an extra :15 per question. If this extra time makes the difference between getting the passage and not getting it, then it's time well-spent.

Of course, if you find yourself going over on both RC & CR on a regular basis, you have a timing problem. You need to make sure that your timing plan includes counter-balances. Where are you going to save time?

A few suggestions:

1) It's not a good idea to rush through an RC passage, or choose a passage to "write off." However, if you realize after several questions that you have misunderstood the material, it's probably not worth trying to go back and re-read the whole thing to salvage the remaining questions.

2) The best problems to drop are CR. Since SC problems are so short, you don't gain a lot of time by skipping them. That's not to say that you should skip CR problems often, but if you find yourself short on time, that's the best thing to cut.

3) While you're practicing, make a habit of analyzing your time usage. What takes you the longest? Are you spending your time productively? Are there problem types, answer choices, etc., that eat up your time? When you go overtime on a problem, do you tend to change your answer, or do you end up producing the same answer that you would have if you'd finished on time? If you run this kind of analysis, you can find safe ways to cut time, while making sure that any overtime you incur is actually helping to increase your score.

Thanks a lot for the suggestions!! I'll try to work on these. Basically I am having timing issues on both CR and RC.

Obviously, carefully reading the stimulus is a very underrated piece of advice as Dmitry pointed out. Going back to the stimulus eats up precious time. Another helpful advice for cutting time on 80% of CR problems is:
1) Really focus on the Conclusion - read it till you've internalized it
2) Personalize the argument; put yourself in the shoes of the author and identify weaknesses in the argument.
3) Once you've identified the gap in logic, dive into the question looking for answers that satisfy that gap - any and all answers that don't address it naturally fall by the wayside

Personalizing the argument is something I picked up from Ron Purewal's videos and it's been an invaluable tool in my arsenal. I'm not an abstract thinker, I deal well with tangibles, so personalizing the argument has helped me drastically improve my hit rate and cut down time by 30-45 seconds per problem.
