I have a test on the general concepts of thermochemistry tomorrow.
how should i study for it since its not based on problem solving, just concepts?
Surely you will have something on the test about the three laws of thermodynamics. Know those three laws AND be prepared to give examples of each. Probably there will be something about convention of signs; i.e., heat going in is + and heat emitted is -. Work done on the system is + and work done by the system is -. Go through your text and/or lab manual and look for concepts and definitions. I hope this gets you started.
