They literally asked some of the sample questions in the math test again word for word, so study the sample questions. There are a lot of questions regarding ratios. Also the proctored test is the same as the online test. Try to remember the questions from the online test to answer on the proctored test. They seem to place a huge amount of revelance on these assessment tests. I rated the interview as difficult just because the math portion of the assessment was tough for me and I did study for it.
