Other than SB and HF, I've been wondering if "academic showcase" is just another hook to separate us parents from our money. The only qualifier for some local and PG "academic showcases" is "3.0 GPA and above." lol
If you are interested in college outside of your local region, you have to participate in nationwide recruiting events. That goes for top-level D1 schools, and for top-level High Academic schools. These high-academic showcases are worth it if you are interested in colleges outside of your local area, they are the best way to get in front of a lot of schools at once, cheaper than travelling around the country to a lot of individual camps. If you want to stay closer to home, then local showcases like PBR, camps at individual schools, or working local contacts, makes a lot more sense.
