So you've been to Core 1 and Core 2. Good start.
You've also experimented with LabVIEW and started making some VIs of your own. Even better.
But now after a few weeks/months/years of not using LabVIEW you wake up and you've forgotten how it all works and all the things you've learned. Whoops. Even worse, your boss reminds you about your deadline that requires some LabVIEW development and, by the way, is right around the corner. Not so good.
Ugh. So what do I do?
