Need some advise

Hey guys, it's my first post on this sub. I have been fortunate to get an offer from ISB, I will be joining the college in June. Some background information about me: I'm 23M Eng graduate working as a software engineer. What can I do before joining to make my academics a bit easier? What should I do during college to build my profile and give myself the best possible chance of landing a very good job? Would love to hear your thoughts.
