apurva, I would suggest, try to glance through the rules from the
MGMAT SC book. I am not sure which area you need improvement on the verbal, but SC is something that can boost your score even the last day as long as you know the rules.
Keep up the good work on th Quant. Also, as Allen mentioned, during the break, talk to yourselves- modifiers, idioms, parallelism, weeken, strengthen, etc....... Just to warm up before verbal

Good luck on your test. Hope to see a 700+
