Need Study tips. I've been stuck in the first 4 parts of JavaScript for days.

Hello! As I've said in the title, I've been struggling with the JS course.

Note: English is not my native language and I've just started FCC last month with no programming background. I'm also spending just 4 hours a day on learning since I'm working.

I'm wondering if I need to read more resource outside of FCC since I've been redoing the first 4 parts.

Currently I'm stranded on the lab tests in arrays. Looking at the test, I realized that I've just managed to pass the first few lab tests of JS by winging it.

I'm wondering if I'm missing something since html and css was smooth sailing compared to JS. Like my memory retention and comprehension of the lessons seems small and now I'm hitting a roadblock.

I'm wondering if there's a good way to get past through this since I don't want to finish a section again and forget how I managed to pass it.
