First formost, thank you to this website, that I have passed my test a week ago. This website has everything one could ask for - the materials, unlimited test questions per chapter, and then you can go back to previous tests and see what area you made mistakes on, and work on that weakness.
I have suggested to admin, that if possible (although I do appreciate their hard work) - if they could also have a link, where you can do 24 questions from all chapters - as if you are doing the real exam. It might be helpful.
Finally, advise to others - if you think you can pass this exam by just attempting to questions on this website, you are wrong - and if you have passed it by doing so, you are lucky!! I strongly suggest you cover chapter 2, 3, and 4. Chapter 5 and 6 are our day to day life activity - however do not miss that either. Make sure you read it. I am not going to boast saying I finished the test in 4 minutes or 3 minutes - but I can assure you one thing, if you cover the whole material, do about 10 tests per chapter in this website, you will definitely pass the exam!!
Good luck - and if you need any advise, I am more than happy to give one.
Thanks
Hari
