I would say the problem the OP had with Orgo II must have been the fact there were two exams. Science courses like that can mean quick death for individuals who do not have abnormally high memory and cognitive abilities. I believe I had a science course like that and got a B in it. However, other homework, quizzes, etc. helped me do well. If orgo II did not offer that as a safety net, yeah, the situation was a trap.
OP needs to wise up and decide when a scenario is bad and eject.
I got a C in orgo II, btw. Yeah, I know it's B.S..
Also, I'm going to have to disagree with some people here. Organic II is like taking two science courses at once. The amount of time necessary for that course is insane. Also, I've been told labs also need an insane amount of time. The credit hour count is unjustified for the most part. But I don't think things will change, as people primarily use orgo for weed-out purposes. Come on, most of us know that, right? They're not going to make the course fair at all.
Taking multiple science courses is not difficult, but taking multiple weed-outs is. Don't take multiple weed-outs, then.
...It's a matter of expectations and motivation and time management. I expect to get all A's and A-'s. If you expect to struggle and have difficulty, than you will, but if you prepare in advance and identify problem spots and have the mental toughness and ability to work through them, you will be fine.
Just one more reason professors just make organic even harder: People come in prepared. Look, it's a game that is not easily won.
But yes, it's an issue of time management (cause, well, we exist in a dimension with time) and knowing when to throw away sleep. Anyway, isn't offering Organic II during the summer a contemporary experimental thing? Because in the past, it was really only offered Fall/Spring, because it was considered most students couldn't do it during the summer.
OP has been ignorant of the facts of the situation and did not know when to eject.
OP, you need to wise up.
Also, I'm not a normal human.
