Failed my first Organic Chemistry Test?

I studied for hours daily weeks before the exam and cranked it up the week prior. Felt very comfortable with all the material and felt like I would do well on the exam. Turns out I failed it. I did not complete about 40% of the exam due to not finishing it. That had to do with me being a slow test taker and a slow learner in general. The exams are geared towards making you go through very quickly. Am I too dumb to pass this class? I put the time in to study and understood the concepts, but alas I am slow as usual.
