Science project help

[JohnBRockerf]

I came up with some new ideas for my science project and I just wanted to get some opinions on it for my project I'm kind of having a hard time naming it but this is what it involves I plan to have 5 subjects 4 of my associates and myself, 2 of the subjects will be asked to do 10 questions from english, 10 from science, and 10 from math all within 15 minutes with the reward being 20$ for whoever can finish the most and get the higher score but all the while being oblivious of the time, my other two subjects will do the same thing only without an reward but their motivation will come from a timer i will set on the table their doing their work on so they will basically try to beat the clock, and finally myself I will try to get the highest score possible on the test just for a personal best with a teacher monitoring me and telling me when time is up and the purpose of this will be to measure their pulses and figure out which causes the highest level of stress on the subjects if you know of any way i can improve this I will greatly appreciate it.
