First advice, you should give more Official mocks to gauge where you are yet.
For your time-management, I am not sure if you make a grid to keep track of your time. I used to do the following :-
65 - 56 - 47 - 38 - 29 - 20 - 11 - 0 (in mins)
0 - 5 - 10 - 15 - 20 - 25- 30 - 36
i.e. you give a 9 min block for every 5 questions. Though, you need to keep one thing in mind that you can cover a lot of time with a number of SC questions that come one after the other. Since you are already good at it, try to devote that extra time to RCs and you won't have to worry about the timing then.
Practice these skills in the mocks and you will feel more confident.
All the best!!
Thank you shameekv1989; my main question here is where do you write this time table? Writing it only in the first page of the note pad, and then trying to come back to it when you're at the the 5th can be very time consuming.
