13 years of school are not that bad, I know people say it all the time and I never believed it but school is really the best time of your life, at least the easiest. Uni is so exhausting, you have to take up so much resposnibility and you have to actually make decisions about your future, back at school it was all "oh well, it's only 3 lessons today, I think I'm gonna feign sickness" (at least the last year, after I had turned 18)
Uni life is different, miss 2 lessons and you've failed. You don't get a timetable, you don't know where to go, you don't know many people... it takes a while to get settled and used to life as a grown up.
As for the English in grade 3, I was soo jealous of everyone younger than me who had English when I first had it in grade 5.
But well, the past is in the past... at least I didn't have afternoon school, like the poor kids who live in the new 12 year to Abi system...
