But yeah, im in my second last year of school, and you have many distractions at the back end of schooling, ya know, games, sport, work, study, revision and parties. If you got a girlfriend, you will no doubt have to cull a large amount of things that you do... but i guess that a lot of school relationships aren't very "productive" if you get what i mean, so just, think what is right for you, and your studies, as they're hands down the most important thing in your life right now
