DD has taken the PSAT twice, I think its good practice to be prepared for the style etc.
My oldest was a ACT ace but not nearly as good on the SAT - the Univ he went to was an either or type submission - he took both and submitted the best, for him it was his ACT score. We didn't do any prep classes. I may be in the minority but I think a kid needs to score somewhat "naturally" as it will help college and the expectations of the college be a better fit. I know kids whose parents pumped tons of money into SAT prep, their scores went up a bit but it didn't make them smarter or better equipped to handle college.
DD just wound up her year, she has great grades and with all the AP/IB weighting her GPA is just stupid high, at least to my 4.0 is perfect trained brain

Finally got her learners permit - ugh, the child cannot turn, she is giving me gray hair. I am reminded that she took 3 years of beginning, yes, beginning ballet. She might be smart but her hand/eye/foot coordination leaves a lot to be desired

so we practice ...........and practice..........and practice
In the fall she officially starts the IB program and is very excited about it.
No college visits scheduled yet, nothing close by is on her radar
She is not sure where she wants to apply but is contemplating Univ of TX, Austin along with there are some east coast schools that have caught her eye. We keep trying to have a reality check regarding the price tag but she still really does not have any concept of what college costs and the ramifications of an expensive education which will be paid via aid or loans. She "hears" the discussion but doesn't necessarily "get it" we are working on it. She is currently exploring culinary school, she wants to bake. Couple of weeks ago she wanted to be a writer/editor and a few months ago it was a pediatric neurologist.
All over the map is a good description.
