It can be done, and EL rocks

BUT...
Why are you wanting to get out of mainstream English? I think THIS is the question to ask - not whether you can catch up.
Don't go thinking that EL is easier, requires less homework, less reading, less writing. UNTRUE!!
It's quite technical with lots of new language to analyse.
You read text books rather than novels.
You STILL write complicated essays and analysis tasks (which are unlike anything you've probably come across before). Examiners expect 600-800 words in about 50 minutes (two of these written tasks plus short answer questions in exam).
You need to be committed and have an interest in how we use language.
There's not necessarily ONE right answer - sometimes there are multiple correct answers. You can't memorize 'correct' answers for typical questions - something that trips up students who think that this will be a 'black and white' subject like a science or maths. It's not.
I'm a teacher. Please think about it! 'Why are you wanting to get out of mainstream English?'
