Talking to your teachers. I'm in the same situation as you, but my teachers are pretty lenient when I let them know what's up. Teachers take on their job because they want to help and if you let them, you will help you. Don't hesitate to tell them you need an extension on your work or for their help. You'd be surprised what they're willing to do for you.But aside from that, does your school have an online resource, like Moodle or something?
