To the OP,
What exactly are you looking for by coming to an internet forum? Do you need other adults to reassure you that you're a good pilot despite your past failures? As an instructor, theres a delicate line to walk between wasting the customers money and over training to sending the student to a checkride too early. YOU as the customer need to speak up if you aren't comfortable and confident. It's really not the instructor's job to spoon feed you every chapter of the FAR/AIM or the PHAK. Take some responsibility for yourself, your training and your career. You have a copy of the ACS I assume? The test is right there.
You're correct that one or two failures probably won't be the end of the road if you take ownership of them in an interview. But it seems like you think the world is out to get you and nothing is your fault. You might have zero failures on your record but no one is going to hire you with an attitude like that. Might want to change your strategy.
