It depends --->
1) Getting Prepared ~ To get prepared a suggestion would go to your local library and getting some "MUST KNOW IN HISTORY" and you can also search up some books, there is a great series called Everything you need to ace (History) In one big notebook.
2) Schools andClasses ~ If you are taking a Honer program you might want to go ahead and study the 7th grade history. If you would be able to tell me what you did this year than i might understand what you will do next year
see, I learned the early settlers all those stuffs and in middle school I learned like Early civilizations.
3) Curriculum~ It depends on Curriculums in your state, so if you can search up the Curriculum in your state. In some places like Asia, you would learn diffrent types of history of that country
