We suggest you go through the article once, it will help you to understand the upcoming exam pattern and with the help of this article, students will be able to understand that which concept is important, Type of exam questions and they can start their preparation accordingly.
As compared to morning session paper, Physics Question Paper of the afternoon session was easy to moderate. The physics section is an easy but time-consuming section and the concept is repeated from previous year question papers. Speed, accuracy and basic knowledge of concepts were required to complete this section on time. Physics section contains 30 Questions, 17 Questions was easy 8 Questions was moderate and the number of difficult questions is 5. The physics paper was more theory-oriented.
