If I could change 3 things at Bangkok University, I would do better. Firstly, the room should be neither too large, which makes the class seem unpopular, nor too small, which makes it difficult for students to move around and should be a comfortable temperature keep students away from getting sleepy. The second, a laptop computer and the projector would never say "no signal detected". It should also be safe to keep this laptop in the room at all times, rather than needing to carry it in and out every day
