Critics have also stated that the computer-adaptive method of placing more weight on the first several questions is biased against test takers who typically perform poorly at the beginning of a test due to stress or confusion before becoming more comfortable as the exam continues.  On the other hand, standard fixed-form tests could equally be said to be "biased" against students with less testing stamina since they would need to be approximately twice the length of an equivalent computer adaptive test to obtain a similar level of precision.

Excel Test Prep has outstanding course materials.
The course is very comprehensive, with 72 hours of instruction for the PE courses, and 78 hours of instruction for the FE-CBT courses. In the Excel Test PE course, concepts are reviewed and many problems are worked out in class. This helps students become familiar with solving problems that are similar to what is on the exam. The Excel Test course is different from college courses, which are designed for their students and cover theory. The course is focused on the exam and helping you pass.
