Test about the search engines and what I like to learn about

I think the test was kind of hard because I did studied, but I was nervous that I almost forgot everything that I studied. Also I would like to learn more about the hardware because the when I grow up I want to be computer engineer so I really like to know how to tare out the computer machine and put them back in to the new computer. My mom's computer is slow so I would like know how to make the computer faster. So I really like to learn more about the computer...
