Hii Lopa,

You can start off by appearing for a mock test conducted free online and assess your performance that'll help you see and judge the areas you need improvement in and then decide if you need coaching or you can go on by yourself. You can either go for self study or Prepare with a tutor. For english prep. You can start off with Word Power Made easy, do this book twice, don't rush but read it and learn for 30-45 mins everyday. For Quants and LR-Di Arun sharma. Giving a mock a week and analyzing your strengths and weakness in terms of topics, score, percentile score and the time you are spending per question is really important.
