Hello sowmya,

Congratulations for your performance,but this percentile is not sufficient to fetch a seat in Nits(i.e you have very negligible chance of getting a seat in Nit).there are many gftis in which you may get a seat.still you have a chance to get into Nits,prepare well for april exam. As there is less time you should work smart. Prepare a schedule as per the known weightages and work evenly for the 3 subjects. Prepare short notes for chemistry from ncert. Also prepare a formulas list for maths and physics. Time management is also an important thing,so work on the practice papers within the given time. Maintain a error notes where you should note all your errors so that it will be useful for revision

Good luck!
