Op not going to call you names, or suggest your young or immature, etc.
Only going to make an observation, from having read the entire thread, (both those providing advice, as you requested they do), and your replies to some of them. Also to your "assessment" of the course and the instructors. Take it all with a grain of salt or take it to heart, matters little to me either way. Just recognize it comes from a person with 35 years riding experience, as well as a former cop.
You say that the instructors essentially provided no truly useful information but only complimented the students on coming out on what appears to have been pretty awful conditions. Having instructed on several topics over the years, as well as a few years of on the road training of multiple constables and junior officers. It is a known constructive technique to acknowledge the challenges the student or persons being instructed are enduring. Not sure if it would be accurate to say that this is all the instructors related to the class. By your own admission several of the students did indeed pass the course, so presumably they got more out of the instructions provided to them, than you did. Before beginning the test, if you were unsure of any of the instructions provided did you seek clarification, (more so on the retest, especially if you were advised that you had done some things incorrectly on the initial test)?
You asked people on this forum to provide you with their advice, and many did so, including according to one poster at least 4 motorcycle training instructors. virtually without exception you dismissed their advice, as being inaccurate or that they provided unusable information as they apparently didn't understand how terrible the instructors on your course were. At one point you made assumptions that were clearly inaccurate, (You concluded that meme was immature and not well versed young fellow), when in fact the fact is she is a VERY experienced rider and she is a female. You jumped to these conclusions based upon her initial post, primarily because she challenged your presentation of the course events. I am not aware of your age, (you referred to yourself as "adults having a conversation"), so I have no facts upon which to determine if your 18 or 45. Doesn't matter your chronological age is, what does matter is your level of maturity.
Given that 5 people failed, although you didn't say how many were on the course, and one quit after a collision, (although that can hardly be assessed as the fault of the instructors or the level of instruction provided, it was perhaps a wise decision by that particular student). Presumably a higher number of students did indeed successfully compete the course.
So logic and rational thinking would lead one to conclude that the competency of the instructors and the level of instruction provided was at the VERY least acceptable. Now having been an instructor, I can attest that not all students learn using the same techniques nor at the same speed and level. In a one on one learning situation these same students seem to excel, and are successful. Perhaps that is where you fall in the learning spectrum, conversely these same students often don't excel and succeed in larger group instructional settings.
You feel that the fact that the school has provided you one retest and when you were still unable to complete the required steps to be judged successful, a cash grab because they say you must now retake the course. One quick question you kept referring to the "box portion" that you failed to complete to the instructors satisfaction on the retest. Did you complete it properly on the first failed attempt? I would assert (based upon the information later provided) that the MTO has set the standards the schools MUST adhere to, that it is indeed not a cash grab, but simply a requirement the school must follow to remain "certified" by the MTO.
As another poster has stated surely while you were waiting for both your tests you must have watched others who completed their testing successfully? How is it then that they presumably understood the instructions provided to them prior to the testing yet you failed to understand presumably the same instructions. I found it interesting that you referred to the instructor who was conducting your second failed attempt as "the chick". Is that because you felt that as a woman she was unqualified to conduct the test? Is it "possible" that as she was providing you with the instructions you simply (albeit perhaps subconsciously), had decided that you didn't need to listen to a "chick"?
What will the outcome be if when you arrive at the MTO testing facility you are assigned a "chick" to conduct your road test? The course test is conducted in a "controlled environment" the MTO test will involve at the end, at least a one block road riding.
Now having read all your posts very carefully, is it possible, (given that several others did indeed pass the exact same course with the same instructors, and presumably the same instructions being provided), that you are unable to grasp the concept of safe riding, in a prescribed manner, during a stressful period, (testing)? This same course has been taken by in all likelihood several thousand students some of whom have passed first attempt, some who have passed with a retest, likely, a much smaller number who failed twice and retook the course, Perhaps some who took the MTO test and passed, and some of whom after careful consideration having failed twice decided perhaps riding wasn't for them.
The course and the testing are designed to ensure a rider develops and can complete safe riding techniques, while being able to follow instructions, under stressful conditions, (testing).
Good luck whatever route you choose to follow.
