For the history classes, learn how to write the essays beforehand, they are very hard. For research, take shortcuts. Do not read the whole article, only the abstract, or you will have way too much work. If your hair shows up in the google meet, it is enough participation.
I had Mrs. Chipetine for both World 1 and Euro. For World 1 just make sure to do and study the study guides she posts every time before the test and you will do fine. I only advise people who really enjoy and are passionate about history to take her Euro class (it is the most interesting but hardest history class in the entire high school). I took both World 2 and Euro and I'd say Euro is substantially harder and more time consuming. Always do the homework for Euro, it will save you so much time in the future when you're trying to study for a test. Despite the homework taking around 2 hours everyday, and the textbook readings being 10+ pages long every night, it helps so much with having a clear understanding of European History, which will definitely make sure you write killer essays in the class. I want to emphasize: TAKE EURO ONLY IF YOU LOVE HISTORY AND ARE GOOD AT IT. WORLD 2 IS A LOT EASIER.
