I hope you do better soon. Studying history is easy if you use this technique:after studying really hard for my history test....... i got a D on the test
1-Read the entire paragraph or two out load (depending how much info is in each paragraph)
2-Highlight the most important parts of the paragraph and write notes and examples beside the paragraph. Color-coding helps when highlighting.
3- Look over the paragraph quickly and take mental notes of things you should remember
4- Cover the paragraph with a paper (or close the book) and recite the paragraph. Aim to say exactly what's written in the book, paraphrasing is fine too.
This technique is very time consuming though.... Good luck with your tests!
