Once you finish driving school they advise the MTO that you are done, that is how you can do the G2 at 8 months. Otherwise its a year before you can try for the G2. The cost of the road test was included in the amount you paid when you wrote the G1 test. I have an almost 17 yr old and we are doing this now, of course he has access to our vehicles so the driving is easier but it is not cheap.
