First Holidays already! That means about another 6 months till the exam!
Personally, I like waking up an hour later than I had to on school days, just to have a good feeling of having holidays. So maybe around 9 am. In terms of doing HWs, I prefer to make a check list of all the things I have to do, and always have it on my table. This is really helpful when you reach the last day of your holiday and look at all those ticks that you have done. It just makes you feel proud about having done so many things and not had your time wasted. Besides check list, try to have a timetable as well. Don't make it contain so many study time. So have a balance between your study time and rest time. But I would recommend you to at least have three subjects per day. And of course, have full day off on Sundays.
So to put it all together in one sentence, holidays are about GOOD ORGANISATION.
