Hello candidate,

You can evaluate the following points and finally conclude what is best for you -

1. First of all,  you can make a list of the topics you think are difficult and require proper teaching.

2. Then you can make a list of topics from all the subjects that are easy and do not need tutoring.

3. You should examine whether your physics and chemistry basics are clear or not.

Once you do a proper analysis of all the subjects you will surely know if you require the assistance of educators or you can cope up and do wonders by self-study.
