Absolutely..that why it is important to read the instructions on the sim. So many people just jumped into the sims without reading the instructions and they ended up not realizing it until they finished the exam and ended up losing a lot of easy free points.
So sim says leave it blank, then leave it blank. If it says enter the zeros, then enter zeros.
Gleim sims are 100% spot on in terms of presentation of the real deal. When they claim their sims are realistic, they weren't joking.
