Thanks Ana and Paul! I agree with the feedback left by Fernanda Rocha. She explained everything very well. That was exactly I was trying to figure out. Here's what she said: A = 100 to 90; B = 89 to 70; C = 69 to 60; D = 59 to 50; E = Less than 40. Although I don't think the letter "E" is used anymore. I would replace the "E" with an "F". Thank you so much everyone for your help! Happy New year!

Hello Mary- It is hard to assume an equivalency because, as you know, an A is equivalent to a range. So, someone who finished a subject with a 98% may get an A, just as someone who finished it with a 92%. My suggestion is that you keep the A, B, C, and so forth, and add a note mentioning that, in that particular US school, an A falls within, for example, 91% and 100%. I have never heard of grades O, B, MB, and etc, as suggested and I went to school and college in Brazil, but it may have changed. Just one more point of view for you to consider... Have a great 2012!

There is a tremendous difference between schools here. One system that I like is A = O (Ótimo), B = MB (Muito Bom), C = B (Bom), D = S (Suficiente) and F = I (Insuficiente). Talking about number grades, there is great variation between schools and between systems.

Hello everyone and thanks for your suggestions ;) I need the translation of the above US letter grades to the number grades used in Brazilian schools. For example, The US school grade "A" would be equivalent to a grade 10 in Brazil if I am not wrong. So a B would be a grade 8 and so forth? And a 5.9 grade would be equivalent to a "D" grade in the US? Thanks!
