This word document contains key information on the factors which encouraged people to go west. There is also a section on who moved west and settled on the Great Plains after 1865.
I have listed the key points which you will need to learn for the exam, but also highlighted key words to help you remember the points.
If you need any more information on what is listed, these notes can be found on bbc bitesize, not in note form, with more detail, but you will only really need the summerised points which are on the document.
If you have any questions, feel free to message me :)
