What are you studying? Years ago i studied full time for a couple years, electronics & computers. I loved it.
Oho, I am curious about what you studied about as well.
For myself, it's Integrated circuits.
How to program digital circuits with VHDL / Verilog.
How to design circuits (Voltage Controlled Oscillators, Amplifiers, Mixers, ADCs...etc) simulate them to check their performance, draw their layout using 0.35µm CMOS and lately 180nm technologies.
Also a lot of theory on Analog electronics (differential pairs, current mirrors, noise generated...) and RF components (power amplifiers, LNAs), some reliability, the trending topics are the Internet of Things and 5G.
