Personally, I learnt with paper charts
first, buy a book or watch YouTube and any other sources you can find, buy a ruler - pencil compass/ dividers and a rubber, sit at a table and practice, often you will find guys with out of date or training charts especially any guys who have done courses.
Once. You have mastered chart work you will know where to go with the electronically aided nav and you will have the satisfaction of knowing you have the ability to get home after the battery
Good luck and happy studying
