@InsaneDipstick My tae kwon do runs fairly differently than yours, but I think it's just practice that makes perfect. I understand the feeling of being behind, but honestly, do not be afraid to ask your instructors questions.
Taekwondo is very repetitive, and therefore you'll be building off the knowledge you get. If you really want, you can look some stuff up on the internet. However I'd say you should ask your instructors.
The first step is always the hardest, I hope this helped :)
