Start with the TN 12th syllabus and complete the chapter first before moving to anything.
While studying, mark down the important formulas, points and diagrams and make proper notes which will help you revise during the exam.
If you are stuck with any concepts, then immediately clear your doubts with the help of your teacher, mentor, or any AI agent like ChatGPT, and then only move to the next concepts.
After completing the chapter, solve exercise questions first and then only move to the question paper.
Make sure that after completing each chapter, start practising from the TN 12th PYQs.
Try to solve the paper in an exam-like condition; for example exam is going to be held from 10:30 to 1:30, then try to solve the complete paper in that particular time.
After solving the paper, match your answers with the accurate and reliable answer key and write down the wrong concepts.
Revise those concepts for which your answer went wrong and attempt those questions again so that no questions come under unanswered next time.
