Disclosure (what 'they' won't tell you)
1. We are NOT a 'waste-time-to-make-it-take-longer' traditional school.
Nor would we advise you to attend one for learning polygraph!
Instead, learn directly from professionals with real-world experience.
2. Such specialties are for selling your
service as a business, not to get a job with.
You will not find a job offer for 9 to 5 employment with such specialties.
Most specialties are 'avocational', which means 'in addition to your regular work'.
Learn this if you want to run your own business with such specialties.
