Im not sure if someone is still active here. However Ill give it a try, since its important to me:
Im a self-learner and bought the books. In order to successfully study with it I highly demand access to the answer keys sections.
I already sent a request a long while ago, and also send the email with a scan of my passport.
Id highly appreciate if someone could finally give me access to the answer keys section.
Thanks in advance and please contact me via email if there are open points.
