What is the difference between primary and secondary school?
In two words: Not much. Well not in a big way anyway. The lessons are better most of the time, and because you're older, you get to do cooler science experiments, more exciting maths projects, and go on awesome school trips.
Everyone's worried that there's going to be a really big scary difference between primary and secondary school, but in truth, it's very similar. Depending on where you used to go, you might have to get up a little earlier, but other than that it's pretty much the same.
