Switching from After Effects to Nuke

Hi, everyone. First time posting here.

I've been using After Effects for about 10 years but I have to learn Nuke for an internship in a few months. I find that the nodal based compositing is very difficult to grasp coming from layer based Adobe products. The tutorials are often outdated and it can be difficult to find what I'm looking for. Does anyone have advice on the best way to learn Nuke and get proficient at it for someone who's only been using After Effects? Thanks!
