I think you have figured it out!
Essentially yes you have to sit all 4 tests!
Hopkins do workshop that orientates the victim in how to take the test, according to ETS you're supposed to have the intro of the test by the inviligilator but they don't do that and so ask for another 1000php off you for a workshop. Nice!
You need to go to Makati or call them up and book yourself in.
They run the S&W tests once every 6 weeks which is very long bearing in mind the results take 15 working days!
Good luck!
