Query: Of some help, but dispensible

I have taught Latin for many years. If one has a copy of the latest Wheelock, then the workbook is dispensible. It is too repetitive and tends towards being excessively easy. If you are a relatively adult learner, I recommend using Betts' _Teach yourself Latin_, which has the answers at the back, or Sidwell's _Reading Latin_, which has a guide for independent study.
