From the PA SE test, does anyone remember the details of the 32 point problem near the end? I think it was number 28. What I remember of it was 1.0 M NaOH was tirated with 18.0 mL of acetic acid. They gave us a titration curve where the equivalence point was ~8 pH at 20.0 mL of NaOH. Is there anythi...

And one more thing... does anyone have any experience with taking last year's National test? It's my first year on varsity Science Olympiad, so I don't have much experience. I know muscular system was on last year also, so if someone could describe that section of the test for Nationals last year, ...

Yeah, I had a 9.7 gram tower that held all 15 kilos so a 23.1 efficiency.

wow, that's awesome! congrats!

at the conestoga invite this year, it was knex, a couple legos, and a popsicle stick.

does anyone know the winning efficiency from the conestoga invite?
