Black Cat Systems has released an update for Elmer, bringing it to version 4.5.0. Elmer is an app that creates sample tests to help prepare for all three FCC ham radio tests. The update adds the latest FCC question pool. According to Black Cat Systems:
Elmer creates sample tests to help you prepare for your ham radio written examination. It contains all FCC question pools for each of the three written exams: Technician, General, and Extra Class.
Elmer will grade your sample test, showing you which questions were answered incorrectly. It will also indicate if you passed the exam. Elmer keeps track of quick questions give you difficulty, and custom tailors exams to emphasize these questions.
