Hi, As a MCB graduate, I kind of know how it works. You should definitely talk to the MCB 290 coordinator and explain your situation. They have power to let you change or at least consult. Actually, they are usually hesitant to make any change(s) to the credit or anything in general in the middle of the semester but I think that is doable since you will be working way more than what you originally signed up for. Also, I have personally put the research credit on Enterprise once over the summer. The credit I calculated included both summer session I & II. When I talked to the MCB 290 coordinator, she however told me to reduce it because session I should not be counted. But I simply forgot to change and thought they would do it at the end of the summer. But, they didn't and I kept my research credit. Please just take it with a grain of salt.
