Not knowing what school you are at, I'm making some assumptions but were you unsuccessful with the MECR & the 170A ? If so was it your first attempt & if so does your training record amplify any problems encountered prior to test ?
If not then you must be somewhat bewildered as the training provider is asking you to leave prematurely - your instructor would have only recommended you for test if he was satisfied with your ability.
Have you discussed this with your course mentor ?
