You can’t expect a training department to crystal ball it every class.
Any training department will always be behind and respond reactively and not proactively as you need a feedback loop to make adjustments.
So they do what they do till failures get above a statistical average then the process starts of determining whether this is applicant or training issues.
I’m suspecting applicant issues.

Show up mentally ready and prepared and plan to work hard.
I know I was and so was everybody else in my class.
