CAREER
A week-by-week plan built for about ten hours a week, with the lab topics ordered so each one reinforces the last.
PYTHON
Pull the running config from ten switches, save each one with a timestamp and diff against yesterday. About forty lines of Python.

Auto-negotiation, link lights, duplex mismatch and why a half-crimped cable can pass a ping and still ruin your afternoon.
STUDENT GUIDE
They are assessed differently and they signal different things to an interviewer. How to choose, and how to do both without wasting a semester.
