Marking Scheme for TN Board Class 12 Exams

The marking scheme for Class 12 science and maths exams consists of both objective and essay-type questions. A clear understanding of the scheme enables you to not only prepare well for the exams but also effectively manage three crucial hours of exam duration.

For example, a look at the maths question paper from 2018 shows that there are 40 objective type questions, and 10 questions (to be answered out of 16) each from short and long answers. If you answer 40 objective type questions in 50 minutes, you can then allocate 45 minutes to answer short-answer questions and 85 minutes to answer essay-type questions. This is just an example and it is completely up to you to come up with your own allocation based on your strengths and weaknesses.

You could also classify the questions based on individual chapters so you know which chapters require more preparation time. In the example we have considered, Analytical Geometry has the highest marks allocated in the question paper followed by Vector Algebra and Differential Calculus. Remember, scoring well is all about effective planning and strategy.
