Hello Shruti,
For VA, which was my the weakest section I alternated in RC and VA, practised 4 RCs one day, solved 40-50 VA questions the next day and so on. For RCs, in particular remember you don't need to solve all question of an RC, because even if questions seem easy options might be tricky so leave them. Solve easy questions in that time. (Do not take any QA question, RC or a DI LR set on your ego. One cannot afford it in an exam like CAT where saving time is everything, learn to leave the questions too).
For vocabulary, I completed word power made easy by Norman Lewis and revised vocabulary sessions of TIME 34 times. (Never SAT and mugged up the words, that's not required. CAT judges you on your analytical skills mainly and not vocabulary). You can take tips from my strategy.
Hope this helps.
