Hi, I just discovered that next year, i will have two courses in the same time slot. I supposed to take one of them (statistical physics) this year (third year) but due missing prerequesite which i'm taking now, i'm unable to. These courses are offered only once a year. i can't graduate next school year if i miss any one of them. I really don't want to be another year behind just for one course. What should i do? thanks!
