Hi! I am currently taking chem 121 through portage learning. I was in the same boat as you. I was looking for the answer to you question, as I had the same thoughts. “I was wondering if the Pre-Exam ends up being your final exam as well? Or, if it doesn't, is the final still in the same question format as the pre-exam?” I was wondering if you could please share your answer that you found! Thank you!
