You should check with your recruiter to determine exactly how much to tag in each section and combined section to qualify for your particular job of choice with the help of Andys specialized online ASVAB course.
In your preparation, you should plan many hands-on assignments similar to the ones you will test during the actual ASVAB exam. Studying this problem means not only learning how to solve all kinds of questions, but also a good calculator free approach.
If you want to work as a Marine, a regular AFQT 35 will not qualify you. You must achieve at least 50 points and reach a reasonable number of points in the General Science (GS) area. This is because doctors must enter medical school/corps immediately after basic training and must enter with a basic scientific background.
The more practical problems you try, the more concepts you learn. In time, you will begin to develop strategies that will help you bypass the requirements of electronic solutions and in turn, give you confidence in your ability to solve any math problem the military might throw at you.
This style will not only help you with your math skills, but you may also find that this learning style will also help improve your score in other areas tested.
