Hello! I am new here và had no idea about the world of không tính tiền pdf's until now. I had a couple of questions regarding these websites:
Which is safer? Can I use either?
What are the chances of me getting a virut from any one of these two sources? How bởi I kiểm tra a file before downloading it onto my computer?
Will I get in trouble for using these versions of textbooks? (I'm in the US)
I'm not super tech-savvy so please feel free to "dumb it down" for me
