My few cents for those edits:

• You're missing a period at the end of "or other reasons" which is the first text marked in orange.
• I think mentioning Amazon and Ebay are perfectly fine. Both are popular places for students to get textbooks and it's cheaper typically than buying form the school's bookstore.
• For the calculator part in the last paragraph, I don't see why it's necessary to explain why you would need a certain calculator over another. It's very self-explanatory.
• For the bit about schedules, I think it needs its own paragraph. I think it's important to have it in your article, but like Adam said it doesn't really fit anywhere. You could make another paragraph and also give some tips for figuring out what classes to take? Such as GUR planning and such? I can help with that since I think you don't get to pick your schedule Dez.
