Gary R. Gruber, Ph.D., is recognized as the nation's leading authority on standardized tests and the critical thinking skills used for them. The Use It or Lose It 2009 Calendar contains
some of Dr. Gruber's best thinking questions and problems designed to keep the mind mentally alert, even as we grow older. Each page of this calendar contains a challenging question or problem
in one of three categories--math, verbal, or logic--with the solution provided on the back of the page. The benefits of using these solving strategies can last a lifetime, even long after the
last test has been graded.
