Don't be shy about practicing at home using Packet Tracer. That is what Packet Tracer is for.

Cisco Networking Teaching Strategy: Learn (text, videos, lecture) - Practice (syntax checker, packet tracer) - Apply (physical labs)

Note: If it takes one unit of time to do something right the first time, it takes 2 to 3 units of time to troubleshoot and fix things that are done wrong. Physical labs are for demonstrating what you've already learned. "Garbage in, garbage out" - don't blame the machines!!
