Does anyone know where to go and get the solutions? My download didn't include the answers so I don't know how I did
I believe the ETS download includes the answers (i.e. "a", "b", "c", or "d") but it does not include solutions. It might be worthwhile to ask for help on solutions to some of the problems by posting on the ETS Physics Problems forum
Does anyonke know a good reference for these types of problems, worked out to refresh my memory?
If I were out of physics for a while and looking for a refresher then I would get an AP physics review book and work every example and problem in the book. I happen to have one such book written by Princeton Review and I think it is very good.
[isbn=0375763872]Cracking the AP Physics B & C Exams, 2004-2005[/isbn]
but older editions are usually cheaper used:
[isbn=0375762272]Cracking the AP Physics B & C Exams, 2002-2003[/isbn]
The chapters on the 2004-2005 book are 1) vectors 2) kinematics 3) newton's laws 4) work, energy, and power 5) linear momentum 6) rotational motion 7) newton's laws of gravitation 8) oscillations 9) thermal physics 10) electric forces and fields 11) electric potential and capacitance 12) direct current circuits 13) magnetic forces and fields 14) electromagnetic induction 15) waves 16) optics 17) atomic and nuclear physics (i.e. basic quantum) 18) fluid mechanics.
Each chapter has roughly 10 or so practice multiple choice questions with solutions (roughly 180 questions). There are also some practice tests that have a total of 140 multiple choice problems with solutions as well. Basically, the book contains 300+ fundamental multiple choice problems with solutions. The book also has short reviews of the material in each chapter and also lots of examples and also a number of free response questions.
The book is basic and doesn't cover all material that can be on the Physics GRE but I would find it difficult to imagine that anyone would consider the book a waste of time. For the person in need of a refresher it will work very nicely for that purpose. For a well oiled Physics GRE problem solving machine it will be a speed bump that can be completed in a day but it can help with problem solving speed, accuracy, and endurance and it can also identify certain equations that need to be memorized for the exam instead of wasting your exam time deriving them. Also, working the problems may even catch fundamental concepts that you need to work on.
