No age, anywhere is a good age to drop out of school. No matter how hard it may seem. Try to stick it out. If you think its bad now, try getting a job without a high school education. School is something you do for yourself, for your future. Don't cheat yourself out of it. Please hang in there if you can. Best of luck.
Don't do it! You'll be sorry! Try to find an alternative, like I went to an adult high school! I finished 11th and 12th in one school year and graduated! That was a long time ago (1979) but I know they're still around! My son went to open campus, you go and do work on a computer, on your own & when you're ready you take the GED test! He got his in 2 weeks! The age is probably 18 anyway so make the best of it! I so wish I'd stayed in regular high school with my friends but I hated school so I just had to get out as quickly as possible! I could've quit back then but I promised my Dad I'd graduate so I did!
