Bio 202 was a different experience for me than BIO 202. First, I think I had the instructor y'all are talking about. That person made the class a miserable experience. I can always talk about that more in a PM.
What made Bio 202 different? First, it is very poorly written in my opinion. You have to use the CD-ROM for several of the units. Those lessons are very well done - but very, very, VERY long. They also included waaaayyyy too much detail. But the exams, especially the midterm which was harder than the final, tended to randomly pick some of these obscure details for questions. So I was never sure where to draw the line as far as diving too deep on the material. I think the course would be much easier if they would not rely so heavily on the CD-ROM, and instead give us outlines like in the other lessons.
Also, some of the lessons which were very long included several labs. So some weeks you will really clock in the hours getting all of the work done. If you have a certain instructor, this person will read the lab in detail looking for answers that match exactly from the answer key. That makes the labs even more time-consuming - though you can always appeal answers and if you can quote the book, you can get credit back. Time consuming and dumb.
The test your knowledge quizes contain many obscure and irrelevant questions (i.e.: What medical condition is caused by a short lingual frenulum?). Instead of giving us useful review questions, you have to wade through crap like that. Also, several of the answers are wrong - and when I would report errors these were never shared nor corrected. So if an answer strikes you as wrong, confirm with your prof.
So my overall advice is this - grin, bear it, memorize the crap, and move on. Buy lots of index cards, as that was the most efficient way for me to learn massive amounts of material for the exam. Give yourself lots of time to study for the exams, too.
