Someone on Facebook posted his new website to study the TOPIK. He has entered in all the questions from TOPIK exam #22 and the website allows you to answer the questions in an un-timed format on-line (aka, no need to print out 50 pages of test papers to practice like usual). You can take the beginner, intermediate or advanced exams and test yourself. I hope he can enter in some older exams too, so show your support to this guy and maybe he'll expand his website!!
