Now that you also claim to be a self-taught engineer as well, I certainly hope you are in compliance with your states laws concerning practicing engineering. In some states, claims you are making by the above statement would be a misdemeanor for the first offense and a felony for the second. Such violations would involve fines at a minimum and possibly imprisonment. Just saying - States require licensing of engineers for a reason.
Yes and no. Only engineers that offer services directly to the public must be licensed by taking the ABET-approved courses.
I work for a private firm and hence need no license whatsoever.
But thanks for the heads up. Or scare tactic, whichever.
