Hey Guys, even though I passed the test quite long ago and have been waiting my paperwork to be processed by RCMP already, just decided to update the thread:
for those who like free online versions of PAL/RPAL practice tests my wife (she, btw, passed the test yesterday) found http://crfsc.safetyquizz.com/ - there were quite good and helpful quizzess. On a plus side - no registration needed. Minuses: limited amount of questions and minor rendering issues in Safari spotted.
