This will help to retain these formulas and units for a longer duration of time. Once a chapter is completed, it is better to revise that chapter first before moving onto the next chapter. This will help in having a strong foundation in the subject as the topics are interrelated. Sequence of chapters: For the physics board exam, chapters like Communication, and Semiconductors are completely theoretical and hence, students can score more in these chapters. Average students should focus more on studying these chapters first before moving onto chapters like Nuclei, Atom, Optics, Dual Nature and then part — 1 Topics to Focus: Definitions, derivations, units and statements. Practice Sample Papers: Practicing is a must. A minimum of six years sample papers and previous years question papers should be practiced. This will help students in understanding the pattern of the examination as well as the type of questions asked in the board examination. During the exam, utilize the question paper reading time to decide the sequence of questions that you are going to follow. It is advised that the students first start with the 5 mark questions.
