I feel your struggle. I really hope i can help you in some way because i really don't understand how you can get G's for grades and i don't know what GCSE is. But i know this, you can go to GED classes at any school or college that offers that program and get a GED cetificate. The community colleges do accept GED certificates after you pass their small test in order to rank you in the level appropriate for you. Also, if you are a good student and continue to progressing in your grades, you can put yourself in a 2 plus 2 program and be transferred to a university, only if you continue advancing your grades and GPA. But i hope this info. will aspire and inspire you to excel you can do it. God Bless You.
