Without going into too much detail, I would say that the simulations can be very tricky in their wording and what they are asking for.
I basically had two simulations that I had almost completed, but when I was going to answer the final part, something was wrong with the answer choices. I KNEW that none of them were right. After wracking my brain for a few minutes, I realized that the simulation was asking for something completely different than what I had been answering. So, for example, instead of answering “what would be the effect if this hadn't happened?” I was answering the simulation as if it were asking “what would be the effect if this had happened?” This caused me to change all of my answers, answers that I was “100% sure” I had right before I caught my error.
One simulation may ask you to post all adjustments (even negative ones) as positive numbers, whereas another simulation may ask you to post them as either positive or negative.
One simulation may ask you to put in a $0 as an answer, whereas another simulation may ask you simply to leave it blank.
These are computer-graded answers, so it's pretty black-and-white when it comes to the right answer. Your professor might have given you credit for putting an adjustment as a negative amount, but the computer won't.
It sounds stupid and obvious, but be sure to read the simulation and understand exactly what it is asking for and how it wants the answer presented.
