Your diagnostics are in:
Now what do we do with the result of this diagnostic test? Compute your percentage (multiply by 4!), then reference these data (which come from the University of Kentucky: Elementary Calculus at UK: 2423 Students over Four Semesters (2002-2004)).
You might look back over the test, and see if you can identify a trend in the problems you missed. Are there things that you need to work on in order to do well in calculus?
A couple of issues:
If you didn't perform well, you might want to take the Diagnostic tests in your text (p. xxiv) to see if you can get a better handle on where you're weak.
You might also make plans to spend plenty of time in the Calculus lab (MEP 457).
