Speak to the boss. It might be that you can be excused the latter part of the meeting, if matters which involve you are in the early part.
Did your boss know that you are studying for this qualification, before you were offered the job? Do they say anything about time off for study?
If then the boss says you have to be there (and I know the sort of team meetings you mean), then would be the time to approach your tutor, it might be that some time could be made up by 1:1s at other times, due to the circumstances.
Hwoever - it just might be that you can't do both, you have committed to attend the study sessions and equally you owe a duty to your employer to attend meetings when they ask you to. I hope it doesn't come down to that.
It might be possible for you to defer the next year's uni study? - although they usually charge a deferment fee, that might be your only option.
