DEAR SENIORS!
please guide me about history of USA. where do i start history of USA? from Indigenous peoples and pre-Columbian history?
I am very confused now. waiting for your kind feedback.[/QUOTE]

Check out the past papers since 2016, and you will notice that pre-columbian history of the native peoples is not a very important topic. Personally I skipped it entirely and saved myself some time. Do a very basic background of the first arrival of the whites, and the first British colonies (all 13) and then go into detail from 1740s onwards.
