I have a few friends who graduated from Saurashtra University and here are some of the things that they mentioned. 

• Attend classes regularly. Make your own class notes.
• Attend laboratory classes. Otherwise, you will face problems during examinations.
• Use the library books and magazines to explore your subjects in depth.
• Internal Examination scores play a major role in semester results, so take these exams seriously.
• Take part in exhibitions and technical festivals. This will help you get rid of your stage fear and improve your interaction skills. 

Also, along with studies try to enjoy your college life.
