When Studying for the SAT, Khan Academy allows me to ask it to give reminders for me every day until the test. This is a good feature, but I have set it to remind me at 6 AM because it can't remind me earlier, for some reason. I'm a morning bird and I would like to to remind me at 4 AM, but it doesn't have that capability, and I don't see why it would be so hard to allow that. 

Thanks!
