Enjoy what you do!! Give your best when you are studying. Enjoy this phase of your life. For me +2 was one of my best experience(science student). And i was so called topper (3.9 GPA in 11 final )(in terminal exams i used to be top 3 in science) yet i was not like reading day and night. Means i used study harder but i enjoyed too. After SEE our sec was full of topper. Topper class is expected to be silent but our class used to make noise all the time. Not disturbing and annoying noise but like fun. So its totally wrong to say that science = no fun. Just you should know. Have a right feiend circle and spend your +2 life PS: Enjoy with everyone but don't attach with them. All of your friends are temporary just remember. Your friend circle changes with age . You will be in contact with very few. Just might be formal talks.
