Trying to see if I can learn something new?

Like take a course but the problem with me is I'm abit of a slow learner and I feel I won't be able to catch on as quick. was looking at a cpr course/certified first aid, saw how much goes into it and I'm afraid I won't be able to keep up or worse I'll remember it all for awhile but forget it later on.

It's like a course I took in college, I remember bits and pieces but because I've not been using the skills I've had daily that not a lot of it has staying in my brain and I've forgotten it
