Hi aspirant,

Top 20 rank percentile will be filled by students above 90% itself. Therefore it is difficult for a 70 percentile candidate to be placed in top 20 percentile of the state. Prepare well, hard work and train yourself in different aspects of the concepts in your next step of your career to place yourself in top rank Put in some dedication, hard work and confidence to reach your goals.

Hope this helps

Alll the best
