Excel formula to automatically create a Class Schedule

[mulalicd]

Please, I desperately need an Excel formula to automatically create a Class Schedule, regarding subject priorities (e.g. everyday German. Maths, Italian, and English have to be from I to IV classes in the morning).

Here you will find the document which I created manually and took me more than 5 hours:

Excel_Class_Schedule_Example.xlsx

docs.google.com

Where to start?

How to make a formula to automatically fill in the cells of the class schedule without overlapping the subject and taking care of the priority of subjects?

Thank you,

Davor
