See your questions is creating illusions. Aiming for high marks needs proper planning and implementation. It needs chapter and unit wise thorough study along with practicing several MCQ through short tests with proper time management.
If you had not done this way, then how will you get your Target will only be known to you. Because without proper studies it is next to impossible. And that too when time is appreaching near for NEET.
So don’t live in hallucinations. Start doing hard work. I think your smart phone and social media is limiting you. When you should be in studies you are discussing your problems in Quora. Why haven’t you discussed a these when you had begin your preparation? Is there any use now, of acceptance what you have said. Time waits for none. Everyear only those will get NEET who have used time to their best to achieve their goal and not others who love to discuss on internet about the problems which actually is not but a result of your laziness.
