Learn English – What’s a word for helpful knowledge you should have, but don’t

single-word-requests

I'm looking for a word that describes practical/helpful knowledge that one should have, but doesn't, — due to the knowledge being less accessible than it should be. Something along the lines of trivia, but more helpful and not, well… trivial. Another similar word was life-hack, but I was looking for something that denoted knowledge more significant or substantial than novelty.

e.g.

"Here's some [practical knowledge that you don't have] that'll make your student life easier."

Best Answer

Inside Information

Taking offset in the knowledge being 'inaccessible' or 'unknown' - I'd borrow a term from trading/business and use something like:

Inside information
"Here's some inside information that'll make your student life easier."

information known only by those most involved with the issue; secret information relating to an organization.
