Just a warning for those whose kids need to take it. If your kid fails this and does the review modules, the expectation is it will take about 15 hours! According to my kid, the process is doable, but long. I suppose those who took AP chem will have less trouble, but my kid hasn’t been in a chem class since tenth grade and it mattered for the test.
I like the process, since it means everyone has reviewed before showing up in August, but I wish my kid had realized just how long the review modules would take him. He is very busy between now and orientation.
