biology is mainly remebering information but it's interesting unless your teacher is bad

chemistry is the second hardest topic you can study

enviromenal science is easy but pretty boring compared to bio

geology = rocks, like find in the ground rocks. i find it really boring

Based on my experience both Biology and Chemistry are hard classes that most people take at the last possible moment before transferring to University or at University. I believe that Geology would be the easiest class to take, but you will need to ask around and find out which Prof. is easiest. Environmental Science also seems easy, but I did not take it.
