TIPS FOR GETTING GOOD MARKS IN BIOLOGY
Know the exam pattern well. The NEET-UG question paper comprises 200 questions, out of which 50 questions each for Chemistry and Physics and the rest for Biology. Know about the negative marking and marking scheme. Each correct question carries 4 marks, the incorrect question will give a -1 mark, and the unattended questions will carry 0 marks.
Use good study materials only. Do not use multiple study materials. It will only lead to confusion. So use only the best study materials and books.
Make your own notes. While studying start taking notes.
Find a good mentor for yourself. You can also take coaching. However, offline coaching is always more justifiable. You should follow the guidelines of your mentor and study accordingly.
Revision is a very important part of NEET preparation. Students need to revise their lessons regularly. Revise the diagrams, images, flowcharts, and topics well.
Solve previous year’s question papers regularly. This will increase your skills.
