comprehensive.  Meaning, all the laws or principles you had learned about Cash will all be used in solving this select problem. So by simply marking these select problems (like an asterisk) when
they were discussed by our teacher in the classroom, you will be guided where to focus your review.  You don't have to review or solve again the other 8 problems because the laws or principles or steps used in solving these simple problems are all used in the select 1 or 2 problems that are more comprehensive.  By reviewing only the select and marked problems you will be refreshed by all the laws and principles you had studied pertaining to Cash or any other subject for that matter.
        Following this technique could definitely make your review easier, simpler, and faster. In the future you can go to a Google Review Center with teachers and instructors who could help you make your review as easy and faster as it can be. I hope this article is helpful to you....
