Is the SIE really that easy?

My firm let me know I had to take the SIE two days ago and got us Knoppman marks, so far I’m 2 chapter deep and making 80-89s on chapter quizzes. I’ve read that knoppman is actually more difficult than the actual exam. I initially planned to spend 3 weeks studying, but tbh I may just do 1.5-2 now. Any advice? Is it really that easy and easier than knoppman? Or am I tripping. For reference, I am a senior in college.
