Stressed

I have 7 projects due this month. I have 3 for english, 2 for chemistry, 1 for history, and 1 for tech. Why do teachers give us so much if they know we barely have time to do it. We have other classes besides theirs. We also have family and friends that we want to see for more than 10 minutes a day. Most people also work for a living. We don't have time to be doing all this work. When will they realize that?
