I have taken three courses through Portage. The A&P were not difficult for me, but Chemistry was not 'easy'. I have taken Chemistry in high school and college, so I had familiarity with the subject. However, this course is math intensive, and there is a lot of work you need to do for each unit. In addition, it has to be entered into the tool - typing in math problems took me a while. I was always cutting it close on exams, or running out of time. I would have been much more comfortable just writing out the problems instead of trying to type out (sometimes very long, complicated) problems on the pc. That said, I did get an A, but if I could do it again, I would take it in person. There were some concepts that were not well-explained, and I had to go out on YouTube or find other sources to figure them out so I would understand them. In my opinion, you will spend much more time working on this self-taught format than if you just went to class a few days a week.
