Mr. Foster is really chill. Do your work and be respectful and you'll do really well in his class. One for sure thing that will ensure your success is: pay attention! He does a lot of demonstrations and explanations, and is happy to help whenever. However, pay attention so you I can make sure you do the assignment properly the first time. I had him for EMP 1, which is a really easy class. So if you know what you're doing you'll be fine. With that said, his explanations are really simple but well done, so you will probably be able to figure it out pretty quick.
Some advice I would give to a student in this class is to do your work. Mr. Foster doesn't assign that much work.
