Very bad form OP. You might want to accept some of the responsibility yourself. The sentence would have been so much better with the word “with” replacing “of.”
Am I not included in the previous posters? Yet another example of miscommunication when words are not scrutinized before posting or while reading. I could have said “with” or I could have said simply “posts” but that is what my mind typed at around 12:30 last night, and isn’t the purpose of this site to help students and parents, not argue over interpretation of words on a screen? So, back to the conversation at hand, thank you @mathmom for that insight, at my school they don’t even tell you what your gpa is past 2 decimals, but they will still use it past 2 to calculate your rank, which brings us to the interesting info that @iwannabe_Brown has offered up. I’m not sure why guidance has to be so secretive about the whole process and calculation. Was it like that at your schools?
