Hey Gopal,

Hope you are doing well!

Well dear,If you want to prepare for NEET,I think you should follow the following steps:

1)Planning:

"A Goal without a plan is just a wish"

              Also,

 "Failing to Plan is Planning to fail"

Hence,planning your time wisely is extremely important,and below are the points you should always keep in mind while planning:

• Always devote equal time to all the subjects
• Always devote an hour to Revision
• Revise on Weekends.

2)Time Management:

"Time once lost,never comes back"

Making a schedule on a per hour basis is extremely important.

• Make  a Time Table and set daily daily targets,work on those targets dedicatedly and don't sleep until its done.
• Also,don't keep studying all the time also keep time for sleeping,entertaiment,social media etc
• Never Waste time,because there are people trying to score high taking drop 2-3 Times but still are not able to,so focus more on the quality of work than the quantity.

3)Select the Right Books/Study Material

                                      "Don't Just Be Busy,Be Productive"

• You must know what to study and what not to,you can talk to your teachers or search on the internet the right study material.
• Also,Practisising more and more numerical problems along with theory is extremely important
• Rememeber Not to forget revising all the formulaes.

4)Syallabus Completetion and Revision

                   "Repetition is the mother of Excellenec"

• Complete your syallabus atleast a month earlier so that you can devote all yoir time in revising and identifying your weak areas.
• And working more on it.
• Revise as much as you can

5)Sample papers+Test Series+Previous Year Papers:

                                            "Practise Unitil You can't get it wrong"

Solving Test papers is extremely important,because that will help you in understanding the things more clearly.Also,you will get an exam like feel.

That will make you polish more and more.

Hope this was helpful!

All the best!

Keep Smiling :P
