Congrats on the score. That technical material is a slog, but totally worth it when you get the signal going. Since you passed, the biggest immediate hurdle isn't the soldering or the setup, it's usually the regulatory stuff and the initial paperwork. Make sure your application for the callsign is fully processed before you start transmitting, even on low power.
When you eventually power up the radio, don't just start talking into it. First up is testing your impedance and signal integrity, specifically checking the Standing Wave Ratio before you send a single digital packet. It’s much easier to fix an antenna alignment issue now than after you’ve spent hours on the air.
Make sure you have a clear plan for frequency usage in your area; even if you are just testing, knowing the rules for specific operational bands is critical. Have a notebook ready for logging your initial contacts and frequencies used so you can track your progress and keep good records for certification. Happy listening.
