Before Goldstein and Marion, there were Fowles and Symon. If Goldstein is a nightmare, then Symons can prove to fill in alot of gaps. Topics are well covered and many example problems are given. Not as complete as Marion, but just as valuable. Symon contains alot of "old school" skills which prove to be very valuable.It's a shame that it takes Fowles, Symon, and Marion to get you through Goldstein, but nevertheless, take a hint and stock up if you are to face the Goldstein book.
