I'm currently studying to be a Pharmacy Tech and honestly, I feel like giving up. I feel like my classes don't explain things well beyond just the concepts. Like, they tell me WHAT but not WHY, and it makes me doubt if I can really make it.

I'm also not good at math off the top of my head, What should I actually be focusing on learning?
And what chances I get to have a position in my store
