I have 2 high school sophomores. My dd took her first psat this year my son did not. They both will be taking it next year. First Question, is it even worth it to pay for test prep for the PSAT. 2nd Question We found 2 test prep courses. One is much more expensive than the other. I can not afford to put them both thru the expensive one. i can do one Cheaper and one more expensive or both cheaper. My dd wants me to send her to the more expensive one. MY son could use more help with his than she does but she is much more likely to really take it serious. Getting a high grade on it is much more important to her than to him. she took the first one this year with no prep at all and she did pretty well.
