Having a hard time grasping things and being able to recall them

Honestly it takes time, especially when you're learning programming; with practice you will start to remember things. It's imperative that you go back and re-watch the videos over and over to soak in all the info and remember what you need to get tasks done, everyone who has learnt here will tell you the same thing because its necessary and we've all done it. Don't let the tasks discourage you, keep using the codes as reference and eventually with practice you will notice you don't require them anymore. Patience is key!! Happy learning :)

Re-watching the videos is good, but I think the most effective way you'll retain what you learn is by putting it into practice in a small project. That's by far the best way to remember things. Think of something you'd like to build, it doesn't have to be super complicated. A calculator, or a guessing game, things like that. You'd be surprised what you can build with the knowledge you already have. But it's gonna be really hard to retain it if you don't use it. So trust me, if you really wanna solidify the concepts you've learned, build something ;) I try to build something small every time I finish a couple of videos or a course and it's worked wonders for me.
