Dear Rachna, as far as packages of Akash is concerned solving all the numerical will surely be enough for both physics and chemistry. But even before them you must very well aware of the NCERT questions. Everyone knows the NCERT factor in NEET. So, you should solve both of them.

Also, you can consider any competitive book for these subjects you will find almost same questions, if you find new questions solve them.

This will ensure that no topic is left unprepared.

All the best

Hope this helps
