Last Minute Preparation Tips For CBSE Class 12 Chemistry Exam
Allocate Time Wisely
Divide your subject into organic and inorganic chemistry and assign time to each. If theory part is easy, finish it real quick and then spend sufficient time for organic chemistry that has equations and bonds. If you think you are pretty good at theory already, then start with organic part first and keep the latter hours for revising the inorganic part.
Be Strong With Fundamentals
If you do not understand the basics, you might end up cursing the whole syllabus. So, it is wise that you thoroughly study the basics of organic chemistry, so that you could arrive at logical calculations even if you don't have time to thoroughly go through each section.
Connect With Practical Lessons
Given that your practical exams are already over, you now already possess a good understanding of the chemical reactions. So visualise the colours and the appearance of the chemicals whenever you study equations or bonds. Visualisation will help you develop an association with the subject.
Highlight Important Points
It is a healthy habit to use a marker and keep highlighting important points while studying. This will help you naturally frame a keyword book and when you go back to revise, you just need to go through the highlighted parts.
Practise Previous Year Question Papers
The best way to become strong with your preparation is by practising previous years' question papers. You can check them out here:
