Is there some type of strategy to taking the asvab
The military suggests that you start studying at least 2 months ahead of your test date for the ASVAB. Focus on areas that you are weak in and make a schedule so that you can easily stick to it and practice. http://www.military.com/ASVAB/0,,ASVAB_Tips_Study.html
You have to study and do the practice test. At least study for two months any extra practice would help and focus on weaker areas.
