How many hours did you study for the drug and alcohol test-dantes

[mtngrl]

I took substance abuse and found it more difficult than here's to your health, but I still passed. I studied about 10-15 hours and I thought I had a good understanding of the information....then I took the test. I felt like I studied all the wrong information because the test went way more in-depth than I had studied for. I concentrated on a general view of barbituates, amphetamines, alcohol, etc, but the test went into specific illegal/legal drugs and their uses. So, study a general overview and then get into the specifics of the drugs and their uses. Also, not a lot of questions about alcohol either, so don't spend too much time on that. I used Peterson's Free Clep Prep.com website for all my studying and passed.
