T test results showed statistically significant differences between the mean scores of the three modes. (P value for all three <0.001) Spearman correlation coefficients between three models are the 0.94, 0.94 and 0.98 (P value for all three <0.001) Conclusions: Although the use of correction formulas has its fans, but the results of this study and the related literature indicates, using the correct formula for the prevention of guessing is not recommended to increase the credibility and differentiation and other methods may be used.
