# Step #2

### Read through the complete syllabus of CBSE Physics (Class 12)

Read through the complete syllabus of CBSE Physics (Class 12) trying to remember what you have heard about it and know about it. Don’t worry even if you feel like you have never heard anything about many of the topics. Be cool and go on. PUT A TICK MARK ON THE TOPICS WHICH YOU KNOW VERY WELL (Hope that there are some portions like that. The more portions you know the better marks  you can expect. Be honest at this point)

For a quick reference I have added the Syllabus here
