Today we took the post test for the chemical composition unit. I would say that this was the hardest test yet in this class. I worked for the whole class period and had rework many questions to double check them. Many problems were about application and some had multiple questions to them. In the end, I guessed on the last few questions as I ran out of time. Since I will need to study this later on, here are some helpful links.

I agree in that this was the hardest test ever. I couldn't even finish it. But I will get started on studying for the final TONIGHT so that I can have the advantage when it comes test time.
ReplyDeleteI disagree. It wasn't the hardest test of the year, but it definitely had some hard aspects of it. I could see how some people would see it as difficult, but to me it wasn't the hardest test of the year.
