Dear Tashimehta,

You have nearly a years time for the preparation of NEET 2019. You need to read NCERT books of Physics, Chemistry and Biology thoroughly.

Know the syllabus well 

Mantain Regularity – Daily preparation and practice are essential if you are planning to rely only on self-study for NEET.

Take online mock for NEET. You should not limit on the number of tests; take as many as you can.

Work on weaker topics - Most students will identify with this. You may be very strong in one subject and relatively weak in the other. Work harder on the weaker subjects.

Don’t get drained by studies. This positive approach will get you a confidence boost and eventually, realisation of your dream.
