Hey!
Yes i agree! I think you should do 3 unit. If you're doing well it's worth a try. A lot of people picking their subjects are very worried about 3 unit being extra hard, hence i was in that situation aswell
But i decided to do 3 unit. It's not as hard as you expect, but you do work at a faster pace, but give it a go and see what happens if gives you the option to drop to 2 unit aswell
but work hard! Plus if you can work hard in ext. maths then you'd be very advantaged! It just takes time and effort =)
ahhh hey i just noticed! A bonnyrigg student too? wow did we REALLY come second last? How shocking is that... ahh just work hard! You can do it !
