If you can't make it through CP training maybe you shouldn't be a pilot. Or study more. Or spend more time in front of the poster doing flows on your own or with your partner. With all your whining about lack of time, what did you do during your two weeks at home with CBTs?
Is the training perfect? Far from it. But I'm not prior 121 and I made it through just fine. Zero failures or duplications of any kind.
Like anything in life, you get out what you put in.
