Hello student yes it's very common to get distracted while preparations but there's nothing to worry its okay to take small break to recharge yourself do watch movies or any thing you want to once in a week so that you can't get bored of studies.

Prepare daily/weekly tagert and achieve them at any cost. Solve as many questions as you can.

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
