无所谓，你认为那个好用就买那个就OK了

  I don't think so. According to the GARP website: 

  Calculators are allowed so long as they comply with GARP's calculator policy.  You may only use a Texas Instruments BA II Plus (including the BA II Plus Professional) calculator or a Hewlett Packard 12C (including the HP 12C Platinum), Hewlett Packard 10b II or Hewlett Packard 20b calculators. GARP will strictly enforce its calculator policy. ( www.garp.com/frmexam/faq.aspx )

  So you have to choose one of the calculators (4~6 models) listed above, with no other allowed.
