Im playing with no magic and i need to gt in to the collage, but i keep failing the speech check to get is there a back door in or what level will my speech need to be

Are you using shouts? If you are, then you can get in during the main quest by saying you're Dragonborn.

There's no back door. It's either magic or shouts.

dint know shorts worked, do i need to pass the speech test to unlock it or take the test but instead of magic i shout?
