If anybody knows if it's possible to take "A&P Introduction" classes

Thank you!

Speaking as one who is an A&P IA and was an electrical engineer before
semi-retiring to restore airplanes, I offer the following observations:
there are no schools less than about 2 years that are wrth damn-all
for A&P work when you're starting from zero knowledge.. No A&P would
recommend you to take the test unless you had considerable experience
and schooling, and then you have to prove to the FAA by log books that
you have the 30 months of experience, then the FAA will approve your
taking the test. You can get some general engine knowlwdge form an
automotive part time school, but it will give you nothing in the way of
aviation standards, FAA standards, and aircraft idiosyncrasies. You
won't know enough to know what you don't know. You would then be liable
to hurt your airplane and/or yourself. If you don't want to give up
your day job to gain the experience and knowledge, you really can't
become competent.

Bear in mind that the FAA allows an owner/pilot to do quite a lot of
work as preventive maintenance, such as change oil, sparkplugs, etc.
there is a list in the FARs, part 43.

I trust this all didn't come across as too supercillious, but aviation
maintenance isn't a trivial operation. A very small oversight or
error could ruin your whole day.
