Feeling a little bummed out...completed 3 day GD&T course through SAE with peers. Imposter syndrome

Hello all,

I hope everyone is doing well. Feedback from experience greatly appreciated. For context, my position at my current employer is brand new, which is a Sr level Metrology Engineer role. I have almost 20 years of experience in roles adjacent or focused on dimensional inspection (CMM programmer, SQE, QE). I believe I have a solid grasp of ASME Y14.5, but I often time have to reference it as a resource instead of remembering each section. I'm fluent with many CMM software, point cloud analysis and SPC packages and would consider myself an SME in dimension inspection but probably not in the application or creation of designs using GD&T.

With this in mind, I felt a bit humbled after this 3 day course as I was the only Metrology focused employee in the class, but there were times where I wasn't able to recite all 14 GD&T symbols, or calculate the bonus tolerance of a given feature at LMC or MMC. The way that the questions were worded used verbiage and syntax that felt foreign at times. The instructor would ask the class questions from each section of ASME Y14.5 2009 and expected the class to answer and there were times where I would keep quiet because the first answer is given on previous answers were wrong.

Now that the class is done I'm worried that I SHOULD have known the standard inside and out and that I should already be a ASME certified GDTP technologist. 99% of my peers in the class are dragon engineers that will apply what they learned to their designs, while I specialize in taking their designs and creating a path forward for each sites inspection team. Is there a difference? Should I feel embarrassed? Have any of you done this before? SHOULD I have been able to recite all 14 symbols by heart (symmetry screwed me up).

Definitely feeling imposter syndrome right now.

Thank you
