Hello student yes you can pursue any degree or clear any entrance examination by hard working and smart working no need to worry just be consistent and determined with your goals. Make daily targets and achieve them at any cost.

Prefer NCERT to build your basic concept and make sure you do each and every example and exercise questions of Ncert before jumping to a reference book, after completing ncert thoroughly refer to the link mentioned below -

1)Rd Sharma

2)Arihant practice book

Solve previous year question papers and analyse them.

Feel free to comment if you have any doubt

Good luck
