ACT240, ACT245, ACT247, ACT348, ACT455 UofT Books

I have 3 books in total, each book is $40. I remember I bought them around $70-$100 (I don’t really recall, so selling them for $40 each) Each book has some of my scribbles but still in great condition. If the school is selling for less, let me know! Please feel free to ask me more questions!
