My daily plan is mentioned in this answer…
Now you are going to do the most difficult task as you have mentioned in your question that is beginning. Most difficult part of any journey is beginning my friend as you are ready to begin so it seems like your passion for your goal the people who have passion the greatest achievers. You have 8 months so you have a lot of time to study just make a plan study two subjects a day but revise Bio on a daily basis because it covers the 50% of your Neet score card and for revising Physics and Chemistry just solve 40-45 questions daily but solving questions isn’t enough set a time limit for you suppose first try to solve 45 questions in 60 minutes then from next two three days start solving 45 questions in 45 minutes then try to do it in 40 and so on. For the revising bio you can prefer mtg NCERT on your fingertips as your basics should be clear so you can use this book in biology.
The most important thing that is don’t use too many books just stick to your NCERT and some NCERT based reference books because the key point is neet is not about knowledge it just test your basic knowledge about the subject but what it actually test is your speed in examination hall in such a pressure you have to solve 180 questions in 180 minutes so there is only one key for high marks in NEET that is speed and accuracy.
