Four entries? This does not bode well for the hobby :-(

IMHO, building at least some of your own stuff should be a prerequisite
for the license.
===============================
In the UK ,in order to obtain an Intermediate Level AR licence ,a
candidate ,prior to sitting a multiple choice type of exam (test) will
have to construct a (simple) piece of amateur radio related kit.
It can be as simple as a sounder to practice Morse telegraphy or perhaps
a simple receiver or a VFO or a crystal calibrator ,etc.
Prior to the construction the candidate will be assessed on basic
soldering / de-soldering skills.
