Hi

I am considering that you are from general category

With  70 percentile

• your rank will be 306900 - 345000  around  as per our rank predictor at

  JEE Main Rank Predictor 2021 - Predict your JEE Main ...

  JEE Main Rank Predictor - Know your expected IIT JEE Main 2021 Rank by ...

you have no chance in NITs/IIITs etc with above predicted rank. You may try for state counselling for Government Engineering College but even for that your chances are low

With 70 percentile, you may not even qualify jee main as per past year trends .

For example,

In 2020, qualifying cutoff for general category was 90.3765335 and jee main 2021 expected qualifying cut off percentile is 90-95 percentile.

So, I would suggest to you focus on your preparation for remaining sessions of jee main so that you can improve your score   ,  go through chapters , practise questions and then revise them, go through mock test paper sample papers and previous year question papers as it will let you know your preparation level and and weak areas so that you can work on them and perform well in your examination.To help you in your application you can use our jee main knockout for which link is provided below
