ASVAB Scaled Scoring

As a tutor for the ASVAB,  I am often asked how to obtain an AFQT scaled score for practice exams. Although I have found methods online for doing so, the results have not been useful. The formula I most often see is:
AFQT Scaled Score = 2VE + AR + MK, where VE is obtained from a WK+PC conversion chart.

In addition, AR and MK apparently are weighted scores that only the Department of Defense can calculate, and that depend on the difficulty of questions answered correctly.

Have you found an AFQT calculation method that gives meaningful results? If so, please post here ... I'd welcome this information, as would other ASVAB tutors and test-takers, I imagine.

By the way, I've used both Master the ASVAB (link at left) and ASVAB: Your Total Solution by REA, and have found Master the ASVAB to be more thorough in its coverage of most subjects, particularly the Word Knowledge section, which is pretty sparse in REA's Your Total Solution.

I recommend finding flashcards for vocab study to speed up the process. Here are 533 terms and definitions for practice:

1-month ASVAB Tutoring Plan

I'm starting with a new ASVAB student this weekend and have been looking for a chart that shows the conversion of raw scores to scaled scores. The student would like to see how close he is to the score he needs to qualify for the Coast Guard.

We're using the ASVAB Top 50 Skills (image link below). My ACT and SAT students seem to do well with workbook-style learning, particularly those whose reading and math foundational skills are lacking. For the first time, I'm also trying McGraw-Hill's Basic Training for the ASVAB AFQT (image link below) for homework assignments. I have found that most practice exam manuals contain subject content that is too general for most students' needs.

Since this student only has a month to prepare (and 5 hours per week study time), I've opted not to use CliffsNotes Cram Plan (image link below), which has proved successful for my previous students, particularly for a homework plan, which recommends about 12 hours per week of study time (hence, the "cram").

Discussion questions:
1) Have you tutored the entire ASVAB or just the AFQT portion? Any specific challenges with tutoring the non-AFQT portions?
2) As a student, what prep materials have you found most useful, and why?
2) Where have you found a score conversion chart for the ASVAB?
3) What materials have you found to be most useful or, if you've used any of the above, what is your take on it/them?
4) Other?

Would be interested in hearing your experiences with this exam prep, the tutoring of which has certainly gained in popularity for me in recent months.
