I just subscribed a short while ago and now realize the Chapter 12 problems don't include the General Problems, beginning with #67 (in Edition 5, which is the edition I have). I want answers to problems 67 - 86. I have done the earlier problems.

Can I cancel my subscription already? I have no need for the answers you provide!

Hi Grover,

No problem, I have voided your transaction so it will not show on your credit card, and also cancelled your monthly billing. Yeah, I thought about doing the General Problems, but it was a daunting prospect and I was hoping the regular Problems would be enough for most students.

I am having the same problem as Grover above. Is it possible to void my subscription as well? I am very sorry for the inconvenience but I only need the later problems. I have no need for these answers either. Thank you, Maxwell

Hi Maxwell, no problem at all. I have issued a refund and cancelled the recurring fees.

Best wishes with your studies,
