Hey Misbah, 

The level of AIATS is slightly higher, being unable to score well doesn't mean you can't do well in NEET. However, yes you need to work harder and cross the 400 mark. If you can touch something around 500s then you can be self assured of your preparation.

For Biology, be well versed with NCERT and then follow up roughly with your aakash materials. 

Physics, sove as many MCQs and problems as possible. This is the only way to strengthen and clear your concepts. 

Chemistry, solve problems and regularly brush through the theory in both your NCERT and aakash books.

Make formulae charts and a handbook jotting down all important points for both physics amd chemistry. The help a lot during last minute revisions. 

All the Best!
