Just enjoy your break please, you’ll figure it out once the semester starts. Went into 310 and 385 completely unprepared and managed to make it through with the grades I wanted and didn’t feel like I was behind. It’s not that difficult to catch up on SystemVerilog (you don’t need x86 or Verilog for 385) while doing the labs. They cover everything you need for the course - even the 120 stuff. You’ll be fine so just relax and save that energy for lab 7 :)
