Definitely recommend using the prepcast simulator, I found the real exam questions to be a lot easier than prepcast, but it really helped train me to read the questions a certain way and forced me to know the topics and processes inside and out.
Leading up the exam 2 weeks prior, I was scoring 64%-75% on the exam simulator which made me super nervous going into it. When I finished I got BL/AT/AT/AT/T
Prepcast really helps you prepare for the exam. Highly recommend it.
Thank you! =)
