Thank you for the A2A @Shalini Shakya
I’m really sorry being late for answering your question before but in my personal opinion if you’re aiming for NEET 2020 self studying using online courses be it of Allen or Aakash is the only option you have!
Don’t waste your time thinking that you hadn’t taken coaching previously but just give in your 100 percent!
Being a fresher is always advantageous because you already have the concepts of 12th in your mind afresh!
I’d recommend once you complete your entire syllabus solve as many question papers as you can!
All the Best!
