That's exactly what I'm doing, my ext 2 teacher is amazing and I really do trust her, but you have to consider all the risks.
But I think I'm definitely going to be doing it as my 10th unit.
Yeah, Ext Two is my 10th unit, and I've never doubted my decision in having it be that. I've never been good at maths, so I figured why waste my time on a subject I can't stand? I'm now able to put much more effort into my Major Work, and at te end of the day, I feel Ext Two is gonna help me get the best mark possible.
