Hello Aspirant,

To be very honest,I would like to suggest that you should make your base strong by studying and understanding the concepts from NCERT.

After you understand  the basic concepts then you may start practicing questions ffrom study materials.

A lso refer various sources to get the sample papers and quick and easy point wise descriptions.

You may also get help from online educators and then practice the questions, as offline help and coaching might not be available.

I hope this helps.

All the best,stay MOTIVATED.
