Pretty easy, overall.
I would highly recommend ecology for students of any grade level. I took it my senior year and found it manageable and still valuable to my education. Mr. Lindsay kept me interested and ended my day on a great note.
I will not be pursuing ecology, but I learned a good bit about environmental science with Mr. Lindsay. We covered purely scientific topics like geology and the water cycle, but the class often took a more applicable turn when we talked about waste disposal and agriculture. My ecological views developed greatly as a result of what I learned.

Advice for students:
Take your lab notebook seriously! For me, it made the difference between an A and a B. Type everything and always be ready for a spot check. Find a couple friends who you can run your results by to ensure that you didn't miss anything during tests or analysis.
