Hie,

First, decide what you actually wish to pursue. Then take expert help or guidance for the proper study plan. You can join some crash course or institute. If you can't focus on self-study, go for group study. But most importantly you need to decide first if you wish to prepare for neet, go and completely focus on that and if graduation then pursue that wholeheartedly. You can't be in two boats. 

All the best
