What are your thoughts on this from your experience? And if you agree that "getting in" with the assistants is the best way to go, how in the world do you go about doing that? Start cold calling or emailing them from some production company staffing lists that exist somewhere?
Networking is definitely important, but I think there's some flawed logic in your teacher's advice. Why would those assistants want to help you? Don't you think that they are aspiring writers too, and want to use their positions to get their own writing opportunities? Their bosses are too busy to read a million scripts by aspirers...so I bet the one script that gets handed over will be written by the assistant. Besides, you're asking for a favor that you have no right to be asking for.
Instead, focus on making FRIENDS. Cultivating RELATIONSHIPS. People want to help their friends, not random cold callers.
As for getting staffed - if you can't find an agent yet, I would recommend you become one of those assistants on a show, at a production company, etc. I realize it's hard - and you may have to be another kind of assistant first (PA, office PA, agent assistant, manager assistant, etc) - but being a showrunner assistant or writer's assistant can be a path to getting a freelance episode, and then getting a staff gig. It doesn't happen for everyone, and it doesn't happen on every show, but I have seen it work for some people. And even if you don't get a script or get staffed, you'll still be learning about the craft and meeting professional writers who may be able to give you notes or, if they like your work, refer you to their agents.
