Keeping sharp when you don't have a computer?

So I've started the udemy 100 days of code python course, and I'm really enjoying it and I feel like I'm on a roll.

My problem is I currently work in outdoor education where I often go away for periods of 5 - 20 days where I have absolutely not access to a computer. I don't want to lose momentum and forget everything I've learned, and ideally i would like to keep learning more in the small amount of free time i get at night. Keeping in mind that i need to be somewhat conservative with my phone battery, does anyone have any suggestions?
