honestly, you're probably better off in a sixth form or collage. so what if you get bullied, happens to everyone, character development really. its you whos gonna succeed in years to come not those bullying you. if you believe you can teach yourself better you need to have a discussion with your college and family and at the end of the day when doing a levels you're going to be self teaching yourself 90% of the content anyway. all my teachers aren't good and i go to a well above average collage, just read powerpoints and i could teach myself better at home but at the same time they have the degrees, phds etc. 5 minutes before your a level exam when you need to go over a concept they're going to be the ones helping you, not yourself. just seriously think about it because its probably not worth it
