I took it yesterday. It's basically the same as in other countries, with at least a couple of nasty questions you gotta get just right. Multiple choice, 16 questions, four options each, one correct one. I guess some of the questions could be Thailand specific. For example hour requirements for getting a PPL are different than under EASA (that was one question I got and messed up). I found what I believe to be all the regulations as they apply in Thailand on the ASEAN Aviation Integration Platform website under Depository > Rules > Thailand.
