Um, guys... I think that there might be some other ways to improve our professor levels besides seminars and tutoring. Look at what I found in a video that came out a couple of days ago...
There is an item called training weight... maybe it can be used as a consumable item to improve the professor levels in which someone is focusing on, or perhaps an equipable accessory like shields, to increase the amount of experience whenever we gain it.
Oh yeah; the link of the video from which the image was taken (The quest appears at 4:54) https://www.youtube.com/watch?v=R8d1TLVcbws&t=295s
