Hello student if you're concerned about Neet entrance examination yes you can secure good rank even without joining any coaching you need to study with determination practice as much as you can as practice is the only key to score good marks in examination like NEET.

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.

Do previous year question paper and mock test at least 2 per week and analyse them for at least 2 times so that you can recognise your weak and strong areas.
