I think Uworld was harder than HESI, but their questions and answers were so close to NCLEX. I did their review series for 45 days non-stop and took neclex the next day, I passed. The material felt familiar. Let me know how I can help with HESI. I reviewed a lot for the exit. I'm not a professional tutor but I can help.
It helped me for both HESI exit and NCLEX. I used it by body parts intead of random testing. That way I could associate the care with the pharmacology.
