Briefly read through modules and spot checked with the unit quizzes. My IT background helped with this class, too, but not much. Took the PA and scored well (in the 80%) range.
Took the OA a few hours later and thought I had bombed it. The test material did not align with the PA at all. There were several occasions where multiple answers were correct, so I just had to try not to overthink it. I squeaked by with a 73%. Wish I had done better … I did not like this class.
Study the material. Even with 23 years in the IT field, I barely managed to pass this.
