Generally sequences and series was pretty annoying. Especially the card problems, they were tough. Overall, there were many formulas to this, and we also had things like permutations and combinations. These were pretty easy, but when combined in word problems, they were really hard. Honestly, I had a little trouble with them. Overall though, after this week I feel confident in sequences and series. The test was a bit tough though. I will definitely need to review them in the future.
Thanks,
