Gainer is a good professor; seems to care about students and has a thorough understanding of the material. Lectures can be very unclear if you have not read the textbook beforehand. There is iClicker, so attendance is mandatory.
Gainer is a good professor to take ochem with. While he is new and is shows in the clarity of his lectures, they are not hard to understand if you read the book. From my observations he's a better pick than Bruice who rushes through material. Gainer legitimately cares and is interested in doing a good job teaching us the material.
Professor Gainer seems very interested in the course he is teaching yet his lectures are extremely confusing and not helpful. The tests are also very difficult and not what one would expect after preparing for so much.
