Trimble is really into geography, but his teaching ability leaves something to be desired. He just isn't really in tune with the students. He can talk on a lot of stuff and will expect you to know little things on tests while leaving out really key things. Study hard and know everything that you can.
M107 DON'T TAKE THIS CLASS. IT'S THE WORST CLASS I HAVE EVER TAKEN AND REGRET IT! Professor Trimble is nice, but that doesn't mean he won't load you with 120+ pages worth of reading over a two day period. He almost refuses to acknowledge that you have work and classes other than his. His soil report is easy to do but his tests are difficult. Also, the books definitions don't apply to his tests, he wants you to use his outdated, very specific, definitions. Oh and not to mention that he is the most boring lecturer ever! He tends to go on tangents and doesn't really know how to structure tests or teach for that matter.
Professor Trimble is very knowledgeable about everything concerning soils and environmental changes in the US. His lectures can be a bit dry sometimes, but he definitely tries to make the material engaging. His midterm was fine, as was the final. But, it's vital to know the info in the books and all the maps he hands out. Overall, he's a pretty good professor.
