practice questions are designed for students who want to test
their skills at the end of the ninth grade level. The test is
not an example of what should be taught in 9th grade. It is a
compilation of the minimum requirements that students should know
by the time they reach the end of 9th grade. The purpose of these
practice tests is to help build your proficiency in the area of
mathematics. The difference between these tests and others is
that each answer has an explanation as to why it is incorrect
(This happens right after you answer a question in the text version
and after you answered all of the questions in the flash version).
Each incorrect answer will then ask another question to see if
you have understood the concepts of the question. The test was
based on requirements for the State of Ohio 9th Grade Proficiency
of Special Interest - (6/17/2002) The American
Book Company has recently used a section of "The
Beginner's Guide to Model Rockets" as an example
of an educational web site in the research chapter of their secondary
schools' workbook. The page they are using is a portion of the
History of Rockets." The American Book Company specializes
in test preparation books and software for high school graduation
tests and exit exams.
--- Begining in May, 2001, the site is being modified to support
Section 508 of the Rehabilitation Act. Many of the pages contain
mathematical equations which have been produced graphically
and which are too long or complex to provide in an "ALT" tag.
For these pages, we have retained the (non-compliant) graphical
page and have provided a separate (compliant) text only page
which contains all of the information of the original page.
The two pages are connected through hyperlinks.
