The first thing I noticed when open the file is that the encoding is possibly broken. Are you using Excel to export a CSV file? If you are, I highly suggest using Google Spreadsheet or LibreOffice Calc, exporting the file with UTF8 encoding. Doing this just about always fixes any important issues.
Another thing I see is that you have the Entry Type column. All are set to Individual. An individual must have both first and last names. Since you are importing colleges, I recommend setting the entry type as organization and putting the college name in the Organization field. Since you already have data in the Organization column, I suggest moving then to the Categories column since those seem to be the same info.
Hope that helps, let me know, thanks!
