Was young I couldn't do good, now I can't do Bad
Not really, no. There are intelligent people who are just plain lazy and have shytty grades. At the same time there are average minded people who are really ambitious and study a lot, so they have great grades.
I agree with that viewpoint to a certain degree (academic pun intended) Average & Eager > Intelligent & Awkward... I reckon if you are book smart it means you are good with theory stuff, but does not really prove applied knowledge well. I suppose the theory can help a bit but not more than that.
I used to do extremly bad in the CCNA course, because a lot of it is theory. But when it came to hands on stuff like setting up routers, switches with routing and vlans, I was blowing everyone out of the water, while most of them were doing better than me at the theory part. Some people are more applied, that's me. I'm glad the place I work for looks at experience more than grades, because to be honest my grades were average, but I probably was able to do more than the average person coming out of education.
