How to prepare and score Good marks in Biology Paper?
Biology is the main subject you need to study, when you wish to have a career in the medical field. Class 11 Biology forms the basis of your preparation for the competitive exams and as well as board exams. It is not very difficult to get a good score in Biology. You need to work hard and have to build up your memorizing power.
Here Are A Few Tips That Might Help
Prepare a good time table – In Biology there are chapters that you find difficult to study. You should keep your time table in a way that you give sufficient time to every chapter. Try to study the difficult chapters first and then the easier ones. A minimum of 3 to 4 hours of study, daily is necessary for good exam preparation.
Have a good reference material (CBSE Study material/ CBSE Study notes) – The best quality and accurate information are available in these CBSE Study material/ CBSE Study notes. You can go for Toppers notes as well. These toppers notes are excellently prepared by experts, after a thorough analysis of CBSE syllabus and question papers.
Solve CBSE Previous year question papers – The ideal way to check your level of preparation is to solve the CBSE previous year question papers. You can know what chapters you lack in and accordingly you can strategize your preparation.
