computer exam sequence and duplication?

[cookderosa]

It's been a long while since I took the CLEP computer exam, and I didn't even take the DSST when I went through TESC, but I'm planning a computer sequence for my 8th grader and for the life of me can't remember which exams duplicate and which are considered "easier" of the lot. Plus, DSST has added a new computer exam that I'll like to plan in for him as well. So, from this list, what duplicates and what would be a good progression of easier to difficult? *these wouldn't be all for this year, but I'm trying to plan ahead* Thanks!!


EDIT: so I'm putting the first two together, can someone verify that this sequence would be a good order?

CLEP Information Systems and Computer Applications -or- DSST Introduction to Computing
then
DSST Management Information Systems
then
DSST Fundamentals of Cybersecurity
