Buying advice

For CFA exams, Texas Instruments BA II Plus is essential. HP 12C Platinum is preferred in real estate for RPN speed. Students on a budget can choose Sharp EL-738 or Casio FC-200V. Consider RPN vs algebraic input; RPN is faster once learned. Avoid ultra-low-budget models if reliability matters.
