Ok so I'm half way in my first year of sixth form and I've been missing lessons due to medical issues. My attendance is gonna be at 88% as i missed one day. I haven't gotten a single warning at all for my attendance but is 88% too bad? If I negotiate with them (if they ever contact me) can I avoid having to possibly pay for exams due to my medical problems? I email all my teachers beforehand that I won't be attending due to illness so it's not like they have no idea where I am. I just hope it's not too serious since I'm only in first year.
