I have never heard of a mechanical aptitude test before I went for testing on that scholarship. I did not do so bad if you consider these tests are based on physics and that I have never taken a physics course before.
On the other hand, I did not pass the test. I guess some might call me a failure. It is not the end of the world really. I will get another opportunity to test. I am going to be better prepared to pass this next time. There is so much study material at the schools library.
I will pass the test next time and be offered the job and scholarship. Afterall, I only had one weekend to cram for the test.
