Just contact the school.
They'll either have next year's schedule available, or at worst, will give you last year's (won't vary much from year to year).
The only problem is that there are many lab sections & you won't know which section you're in.
For classes with a lab, you might all have class 9-11 Tues & Thurs, but there will be 6 sections of lab that all meet at a different time.
