I graduated high school, but before I did I got a decent score on my SATs (1660) as well as an Associate's Certification on Solidworks, a 3D Modeling Program, big resume help.
I also scored an 85 on the ASVAB Exam, a military aptitude test (0-99,you need a 31 to be able to be enlisted in the Army, average scores fall between 35 and 50).
And by the end of next week I will have built my first custom PC, so overall I'm pretty satisfied with what I accomplished before going into the real world.
