Not good enough

I'm a 1L student struggling in the beginning of the second semester. Despite the good grades I had from the last sem, I can't help but feel lost. I'm currently fixing my study habits but I always end up feeling knowing just the surface of every lecture, every subject. Some of my classmate has already grasped the important principles. I don't know what I'm doing most of the time. Any advice or words of wisdom?
