ray:

All my amateur radio studying was done a long, long time ago so I am
unfamiliar with practice materials available these days.  Might I
suggest, however, that you formulate your own problems and solve them?
You'll learn a lot that way.  A simple example:  anytime someone
mentions transmitting on a certain frequency, calculate the wavelength
in meters; do the same if a wavelength is given (though you'll find that
the wavelengths given for ham bands are only *very* approximate).  Also,
just drill yourself on the various prefixes, e.g., if I have a resistor
of a thousand ohms, how many megohms is it?  Or -- and this is a
real-world example --if my ancient tube-type TransOceanic draws a
filament current of 50 miliamperes thru the series filament string which
is across 9 volts, how much power am I consuming?

Your imagination is the limit.

As to the T antenna on your stereo, it's most probably an antenna for
the FM broadcast band.  At this frequency, grounding your stereo won't
make a lot of difference.  However, putting your antenna outside with a
longer run of 300-ohm twin-lead (that's the impedance of your antenna
and what your stereo is used to) *will* make an improvement.
