Here are son preparation Tips: -

First of all go through the NCERT,  believe me each and every line of NCERT is important. Any line can be your question of next year.  fix your time table and follow it every day. Make your target of every day and make sure to complete it by time. Try to solve the questions of important topics and every chapter after completing it. Try to complete your syllabus ASAP and then jump into last year question paper. Solve at least last 5year question papers…

I hope it helps. All the best.

For preparing for neet you need to clearly understand the chapter.Understanding is the key.
Make a timetable.Give equal importane to all the subjects .
Try learning extra.Refer to different books and study materials.
You can also take oline tests conducted by different coaching institutes to have a better idea about the question pattern and get you more aquainted with the examination.
