Yes you should be able to, my friend failed his English language but he could only do sixth form is he resit his English language in January when the year 11's do their English exam in January.
If you work hard and manage your time well it's possible. What do your teachers suggest?
they did say that I can but i would not like to do BTEC I would like to do Alevels. I wasn't concentrating at what they said as i was annoyed with the results I got.
