Americans who passed part, but not all, of the GED test are rushing to finish the high school equivalency exam before a new version rolls out in January and their previous scores are wiped out. About 1 million people could be affected.

With the new version, test takers must use a computer instead of paper and pencil. The test itself will be more rigorous and cost more — at $120, the price in some states will be significantly higher than previous versions. Some places may subsidize all or part of the cost.
