I'm Pre-Med, so I can't help on the Finance course. I have, however, taken several summer courses. Last summer I took condensed PHY 231 and 232 courses. Seems similar to what you're taking, in terms of course length. Honestly, due to the speed that we went through the material, I found it a bit more challenging than expected. I did, however, have work 40 hours a week as well as a cross country coaching job, so I was always a bit short on time.
In general, summer courses seem a bit easier than the full semester courses offered at the university, IMO. They're just a bit rushed. Time management and keeping on track with course work were the biggest challenges.
