Ban vocational school formula collection?

Good day,

I'm currently training to be an industrial electronics technician and am now writing my first assignments. We have three books that we're using: a technical textbook, a table book, and a formula book. A teacher said we weren't allowed to use the technical textbook and formula book in our assignment. But in one of the upcoming assignments, we have to take values ​​from a table that only exists in the formula book. It's a table with 32 materials and various coefficients.

How can you write an essay on topics you can't remember and you don't have the notebook with the tables?
