Once you get in the CS, you will have a chance to move up. It may surprise you that there are several 2nd lower grads who are now bosses (superscale) of their 2nd upper and 1st class classmates/cohort in the CS as well as SB.

Your academic qualifications are but 1 aspect of your capabilities. How you approach challenges, your ability to see the big picture, your communication, leadership and management skills are all equally if not more important. You also need to have the energy level. Some of these people work 12 hr or more each day and are still on the go the next day.
