I hear it's a good course that is worth it's money.
That said: The math checked in a case interview is not difficult. And solving a math problem in 30 instead of 60 seconds won't shift the needle on your case. Most people do not need the actual mathematical practice - candidates who studied clear non-quantitative courses throughout highschool and university might be an exception.
The only thing that makes it so is the stress of sitting infront of an interviewer that is waiting for the result. This is a feeling that you can't simulate in an e-learning course. The only way to practice that is to do practice cases with other candidates or coaches.
That's why I recommend most candidates to not spend time on these math courses, buy invest the time in more case prep - but you need to make a decision based on your level of comfort with the math.
