Soldering Iron, Solder, Wire, hand tools, (you should be able to take a radio apart)
I have parts cabinets with parts. You can buy a kit of (100 each of most common resistors) & ( 20 each of common capacitors) I know you can make it through school with out soldering two resistors together but......it is really nice to go home and make a small amplifier out of parts in you parts cabinets. It is too early to get ICs but some PNP and NPN transistors (2N2222A) will allow to make something.
A 20Mz function generator is good! (sign wave and square through the audio range) If you need a RF signal generator it should be a separate box. (sign wave)
That oscilloscope looks good! Did you get probes with it? Usually I get 10:1 probes but it is nice to have a 1:1 probe for small signals. (1:1 probe works with week signals but the probe is not as fast.)
Don't forget the used market for test equipment.
