How should I prepare for class 12
Hey aspirant,
You preparation for class 12 totally depends on which board exam you will be giving and for which stream. You have not mentioned these two important things.
Nevertheless, if you are in Science Stream from any board (ISC/CBSE/GSEB or any state board) then you might have to work a little harder. Thoroughly go through each subjects and the theoretical portions first ( for Physics/Chemistry/Biology). Understand the basic concepts, basic concepts are the most important ones. And then go for complex problem solving, logical questions, numericals, etc. For maths calculus is the most important part along with conic sections. Make sure you understand all the relations and logics and then practice a lot. It gets easier with practice. Try to complete the syllabus 6-5 months prior to the exam. For the last few months just keep on practicing previous year's papers and mock papers. Try to solve the questions in least possible time but do not skip steps.
Otherwise, if you are from Commerce/Humanities then also thoroughly go through yoir texts, especially economics and pol science fir humanities, and accounts and mathematics for commerce. Try to solve as many question papers as possible this not only boosts your confidence but also gives you a good practice on time management, thinking activity.
Hope this helps,
All the best!
