IMHO, spend the money elsewhere like Total Control or similar advanced street riding courses.
M2 Exit is not easy, but it's not designed to fail you either. If you have been riding, and fully capable of shifting, respecting the posted speed limits, ability to check blind spots, able to stop the bike with 1 foot down, and observing your surroundings 100% of the time - including empty driveways, entrance/exits of the mall, etc. You will pass.
The MTO tester is really looking at how comfortable you are with the bike. If you are duck-walking out of a parking spot, yeah, you are not ready. If you need both feet down at all times when it comes to a stop, you are not ready.
Remember, some of the MTO testers are also riders. It's good to have a chat with them before the test starts (when they are checking your bike's signals) to set expectations that both of you are comfortable. I've posted my two questions before, and here they are:
1) When going on the highway, I am supposed to merge safely with ongoing traffic speed. I understand the posted speed limit on the 401 is 100km/h, and to be realistic, majority of drivers exceed that speed. Are you okay with me matching traffic speed to merge safely?
Response I got: "It's okay to speed up, match traffic speed, but once merged, you have to drop it back down if that's the scenario. Do not do anything crazy like 120."
2) Blocking position - are you okay with me swerving around potential hazards like pot holes & debri on the lane?
Response I got: "Yes, perfectly fine. Avoid hazards"
Now, that's my MTO tester. Take this info for whatever it is worth because other testers maybe different.
And yes, the walkie talkie piece they give you maybe crappy, and you cannot talk back, but you top your helmet whenever you cannot hear the instructions clearly.
The joy of the test is they'll be following you in a car. Usually well in advance they'll tell you to turn left or right, or perform a lane change. And I would say 99% of the time, they've already blocked the traffic for you.
Three things you have to keep doing throughout the test:
1) Move your head left and right constantly - because the testers cannot see your eyes from behind you, that unfortunately is the only way they know you are observing traffic and hazards around you at all times
2) You need to always leave at least 1 car length of space between you and the vehicle in front of you, regardless whether is rush hour or not. Otherwise you'll be deemed following too close.
3) Always use the right lane (slow lane) as your default riding lane. Left lane is for passing - this is a concept that a lot of drivers cannot comprehend.
There is not real trick to passing the exam. If you ride, ride often, comfortable with operating your bike, being alert and ride defensively, comfortable in riding with traffic, you will pass!
