If you are going to waste , so much time asking such questions , then you won’t be able to score.
It’s never too late, is not applicable after it’s too late😅. Now don’t think of your expected marks , just focus on completing the syllabus and practicing questions.
Now it depends on you and your hardwork that what score you will achieve, but you can’t waste this 6 months more only thinking and planning about NEET 2021.
Make a flexible plan within a hour today and start executing it to the level best from tomorrow itself. Your each day will count , Mark my words.
