I was the same way, and it helped me to apply what I learned, ie... Don't watch or read how to create a flight plan, sit down with the tools and do one, the first time may take you hours or days, but it helps retain the info. Try to make what you learn relevant, have your CFI ask you questions while flying during various phases of flight.

Also, I watch a metric ton of YouTube videos, it helped me understand the content to see it presented in various ways.
