Re: Test writing

If I'm writing fossils, I generally take forever because I'll be combing our fossil collection for unique/interesting specimens to write questions on. Otherwise, 10-15 hours for a decent test is pretty standard. For higher-tier invites/competitions, I will generally take more time to double check t...

Re: Circuit Lab B/C

I want to make everyone aware of 3 exams that have been uploaded to the test exchange for this season. Ashernoel and I wrote a Boca Raton / New Trier tryout exam that has been posted to ensure our alma mater are not receiving any special treatment/opportunities for circuit lab practice since we are...

Re: Gravity Vehicle C

^ What sciolyperson1 said And compression springs especially are very finnicky, and I learned this the hard way last year. However, tension springs don't have the disadvantage of inconsistency so it may still be worth looking into. Has anybody experimented with braking/slowing methods other than th...

Re: Gravity Vehicle C

My current design, not built yet, has a spring on the end of the axle. The wingnut will start to slow down from the spring, but will not immediately stop the vehicle. I'm sure this is a common idea, though. Has anyone tried this? I've been trying to find out how this works as well, but I was wonder...

Re: Gravity Vehicle C

my vehicle is experiencing major skid when it brakes. My wheels have good traction but I dont know what else I can do. Clean the floor. Clean the wheels. Good suggestions. Additionally: how fast are you going when you brake? What kind of brake are you using? If youre going fairly fast and have a "l...

Re: The University of Texas at Austin Invitational 2019

Statistics from Circuit Lab B/C. The scores were certainly a bit lower than I expected, but I also wasn't overseeing the grading of exams and I typically like to give a fair amount of partial credit (which may or may not have been the case since a clear grading rubric was not made). This test was wr...

Re: Circuit Lab B/C

I'm new to circuit lab this year. How do I study, besides the powerpoint and the youtube videos? I would start by practicing circuit analysis, since this is a key aspect of the event--one that no binder can really prepare you for. Analyze a lot, and many different kinds. On tests, I always run into...

Re: Gravity Vehicle C

You are correct, you would have a faster time with a shorter device that you described because you would hit the peak velocity earlier. However, the difference in time will not be worth the loss of accuracy you will experience. Larger wheelbases will result in less deviation from the intended path ...

Re: 2020 National Tournament: North Carolina State University

As somebody in North Carolina, I would like to add that not only will the tests probably have length, they will also have a width. The length will probably be 11 inches, and the width will probably be 8.5 inches. Tests with lots of questions may even have height. This isn't official confirmation, s...
