That's what my friend said too. He got 50%+ average and he only used Uworld and pass the test. However, he made notes of all the rationales. Did you finish the 1,900+ questions? I bet you'll make it...
I felt the same after the Orientation. It was so stressful esp in rehab. Everything is just fast-paced. However, when you get used to the tasks, you'll be able to catch up and have your own routine....
