what’s the biggest barrier to success in college??

PLEASE READ THROUGH THIS!!! So the file that i uploaded does not answer the question what’s the biggest barrier to success in college?? Also its my shitty draft. the Book we’re gonna work on is by Linda F. Nathan ” When Grit Isn’t ENough”. Can you just ged rid of dont need things and add yours on the file that I uploaded and please don’t use any fancy professional words just because i’m an ESL student. A lot of my paragraphs from file does not answer the question, so can you stick to the question and don’t plagiarize please thank you. The source can you just source the book itself thank you
