Well, I've never actually did summer school, but I was signed up for this reading course that was held once every other week for six weeks. It sucked and we did have homework to do, but in the end, my English and reading skills have never been higher. So my advice to you is suffer through it and reap the rewards. But most importantly, do your best not just for your parents, but for you as well. It all pays off in the end :)
