Hello Rachna

There's no need to worry dear even if you are a dropper you can definitely get good marks but if you are looking for easy and some shortcuts to score well then sorry then there's no way other than studying and pracising lots of questions . You can follow these below tips to prepare well for neet examination :-

• Focus on ncert first "- first of all go through ncert to clear your basic concepts and have a good grip over it as many questions in neet are directly based on concepts from ncert and you can take the help of reference book to understand the topics you find difficult to understand, Ncert is really good for clearing your basic concepts especially for biology, you can follow books like Trueman's biology as well for reference and follow books like hc verma for physics and op Tandon for chemistry.

• Practise questions :- After finishing each chapter you should practice numericals and mcqs from that particular chapter. You should practise numericals and mcqs , go through past 39 year chapterwise papers of neet aipmt book for each of Physics, Chemistry and Biology by arihant and once you are done with the complete neet syllabus go through mock test papers

Make a routine :-You can make a routine as well and try to give at least 8 hours or more to study , your routine should revolve around studying concepts and practicing it by solving mcqs and numericals.

Revise "- You should make a list of important formulas in chemistry and physics and important diagrams in biology etc. and you can brush them up weekly and keep revising your concepts at regular intervals

Just be positive and prepare well and you will be able to score good marks

I hope that it helps you

Thankyou
