Don't worry! I just said it was peculiar that your teacher had a strong Belgian accent because it is a rare occurrance, that's all :)
As to suggestions... *Thinks, hard* Well you can go on reading and watching anything and everthing in English, that'd really help further improving your English, but as for the actual English class, I don't have any idea as of yet...
Does your high school have different English level classes? If so, you might want to ask to go on to an advanced level, if you feel up to it that is.
Mine did and when I entered high school I was promoted to advanced and then bilingual English class. Let me tell you that bilingual level was a challenge at first, maybe for two or three weeks but after I got used to it, it was more or less a pleasure cruise: we got to do all the fun stuff like improvisation plays and debates and such when the others were stuck with grammar classes, mouahahahaha! *evil laugh* (we still had some literature lessons and all, but in the end it was always leading up to a debate of some sort...)
On a more personnal / egotistical note, I'm really happy these days...
I am finally a second year Master student and I -FINALLY!!!- started my specialization, i.e. subbing, dubbing, voice over and multimedia translation.
I am so happy to have hung on during all those years of general translation, with loads and loads of general classes (taught in French) when some of my teachers thought I'd never make it just because I suck at learning by heart and we have to learn general classes by heart... so YAY for me! *Cheers!*
This said, I'll stop with the "me, my, myself" moment :)
