Hello Aspirant,

For preparing for BITS, you won't be needing years for preparation you could easily prepare for it within a few months and the strategy to get top rank in BITS is simple as follows:

• First prepare well from NCERT and then practise every question paper set from ARIHANT few weeks before BITSAT
• Think as less as possible about the score before the exam
• Have faith in yourself

Hope this helps

Good Luck
