Alright this needs to be answered in two parts
- Assuming you’re a single degree student
So you’ll need to do 15 credits of open electives apart from your CDC’s and DEL’s, so you can take up your minor degree accordingly and fit it up in those 15 credits of open electives.
- Assuming you’re a dual degree student
Apart from MSc Chemistry all other dual degree students need to complete (15+12) credits worth of DEL’s, chemistry students need (12+12). Usually if you want to take up a minor as a dualite a summer term after your third year fits your equation perfectly and the courses you do towards your minor will count as open electives, however a maximum of overlap between major and minor degree courses is allowed only for two courses.
