If you were doing Algo through your school, I would say go for it, but VSV is completely terrible. It is a very hard subject, but the workload isn't obnoxiously high if you can understand the (difficult) concepts. Coding experience is helpful, not only because some SACs require code but also because it teaches you how to think about solving problems using pseudocode (handwritten code which is like a series of steps in English). If you are doing it for next year, I would recommend learning to code Python during summer as it will put you far ahead of everyone else in the class.
The maths is at a high level, but methods knowledge should be fine to get you through it. IF YOU DID NOT DO METHODS 1/2 DO NOT DO ALGO.
I did Data Analytics with VSV this year.
For the content they gave us to learn, about 75% was copied from the textbook. In the 25%, there were dozens of mistakes and the content wasn't proof read. Teachers have low respond times or don't respond at all, and they want you to contact them through a weird mix of their online messaging service and email (and we were not allowed to use their messaging service at one point). There are no video calls, or ways to properly ask a teacher to explain an answer like in face to face teaching. They screwed up my enrolment info, meaning I was enrolled a week late. The online learning cobbled together by my normal school during COVID was levels of magnitudes better than what VSV did.
