I'm in the same situation as you, I've got really bad as results and i know all my friends got As. I'm re-sitting my exams in june. Don't worry too much about As results, A2 results thats are important ones, as long as you work hard next year I'm sure you'll be able to get good results. And if they are real friends they will not laugh at you. Talk to your teachers they'll know what to do! If things don't work out there will be other options, don't think it's the ends of the world because it's not!!!! You have not truly fail until you give up so keep on going!!!
