After I went through all the video tutorials and PDFs, which were well organized and helpful to review the material, I put the audio files on to play on my car speaker, so that whenever I was driving, I would be absorbing the material repeatedly without having to carve out additional study time. My commutes to and from work doubled as study time.
The study questions were also very helpful to go over after the end of each lesson. I did the Agents of Change 75 question mini practice exam as well, and my score on it was very predictive of my actual exam score. My scores on that practice exam, the ASWB 170 question practice exam, and the real ASWB 170 question exam were all within a few points of each other.
