P.D.
Check with your daughter's school and see what they recommend. I used to teach a preparatory test for the ACT to high school students. I really think it was beneficial to them. It was a five week course after school. I have since retired and I do not think that the district does it any more. The JJC course might have too many high school students enrolled and your daughter might feel outranked by their age. That would be a decision you would have to make together. I think it is definitely worth your while to have her take some type of course introduction. It is very thorough and there is a book available that the students use to study and answer sample questions. It makes them think, reason and quickly answer and then go on to the next question. It is a good learning experience. Your daughter will gain confidence in taking a standardized test in a time limit situation which is a "trial" test only!
