For SC :
Dont read option A again . Also incase you find the mistake out inthe question dont read any options where the mistake is repeated. This way you will save time.
Regarding DS :
Dont solve till you get the answer completely .
For linear equations remember the rule, that for a 2 variable equation, you need min 2 different equations to solve the variables.
Find below some generic tips on pacing . Honestly speaking on test day all that will matter are your nerves, and your ability to leave the question and move ahead after 2-3 minutes in case you find it difficult. Dont get stuck onto one question unless you have loads of time .

3 41 41 To understand this table If you are doing the verbal section after the first 25 min ( Timer will show 50 min) :- Incase your someone who starts slow , and then picks up pace you should beat Q12. Similiarly, you should be at q14, if you are a steady test taker, who takes the test at a constant rate for every question .
Ideally slow and steady is just a benchmark for you to know whether you are too fast , or extremely slow. Therefore after 25 min ideally you should be somewhere between the 12th and 14th question .
