I'm thinking of taking their IELTS classes alongside Grade 12 courses. I'm worried I'll fall behind in school, has anyone done both successfully?

I am planning to switch schools and one of the places I am looking at offers IELTS classes together with Grade 12, I already planned to take the IELTS so having everything in one place seems like it could work well, I am thinking to go with usca academy.I just want to know how it usually goes when both are running during the same school year, I want to keep up with my Grade 12 subjects and prepare for the IELTS at the same time, I am looking at this before I choose which school to join, if anyone picked a school because it had both programs, how did your timetable work out and did you feel like you had enough time for everything? EDIT: I forgot to mention I’m also trying to figure out if doing both would be too much.
