DSST Introduction to Computing Exam
Do you know a lot about computers? Almost everyone knows how to use a computer these days, but some people are more knowledgeable than others. If this describes you, the DSST Introduction to Computing test could be a good way to earn college credit.
DSST is a prior learning assessment program designed to help students earn college semester hours for what they already know. If you grew up around computers or picked up computing knowledge through jobs or hands-on training, you may be able to test out of an Introduction to Computing class and earn college credit at the same time.
The DSST Introduction to Computing exam covers these topics, with the percentage of questions for each topic shown:
- Computer Organization and Hardware – 20%
- Systems Software – 15%, 3) Application Software – 15%
- Communications and Networks – 20%
- Software Development – 10%
- Social Impact and History – 20%.
To study for the DSST Introduction to Computing exam, you should check out a DSST Introduction to Computing study guide, which provides a detailed exam outline, practice questions, and other resources.
You may also want to check out some common reference books. It can be helpful to compare an exam outline with the table of contents for each textbook and then study the material that overlaps.
