System design is killing me

I have completed learning system design concepts from jordan has no life videos, hello interview deep dive videos and github repos. I haven't seen solutions for questions till now So far concepts are clear but when i am trying to comeup solutions on my own, for most systems its not perfect. Every question seems to have unique concept, unique kind of algorithms knowledge. Is there any better way to learn system design for interviews? Do we have some must do questions list? Is learning all frequently asked questions the only way to learn system design
