Making websites for businesses while going to school?

Well, here's my say on this. It will screw up your school. Unless you can balance school between that, it will get you messed up. You can give it a go for a bit, but once you think you can't handle it, just finish your last one and stop. It's a time consuming job, you can't do it unless you have that time.

However, that is just my say in this. Maybe you can manage better than I can.

I've been doing that for about 2 years now and it's fine when you start out (in Grade 9, in my case) because there's not very much homework for school and you have plenty of free time but it's started getting harder for me to balance because I have so much school work and then extra work on top of that.

If you have enough free time, sure, go for it, if you don't, I would advise against making websites for money while at school.

I designed and developed my school's website over the summer, and then managed it during the school year. Building a good website and going to school at the same time isn't easy. I spent hours of work on just one site each day, solving problems, debugging, adding requests as they came in from administration... it certainly wasn't easy. I also had to maintain the site during the week, so even when school stared, I came home everyday to an email inbox full of things that needed to be changed, pictures to be added, sport's schedules that needed modifying, etc.

If you are really set on doing both, I would suggest only doing the development on weekends. Though this will take up your free time, and make the development process slower, it let's you separate the school work and web development,
