Auto Hide Columns

Hello Everyone

This is my first post and I need your help I’ve not written VB scripts before but can mostly understand them . I have created a form with a number of different drop down lists (which I’ve attached)

What I need to do is if C6 changes to Nursery hide columns G, H , M and N, Junior hide columns E, F, M and N and Senior hide columns M and N hide

But if School name changes to The Royal High School Bath then if C6 changes to Nursery hide columns G, H , M and N , Junior hide columns E and F, Senior hide column E

I hope this makes sense and I hope someone can help me

Thank you
