You've got us lost, I think!
We've no idea from your post which as to which country you're in or which level of education it is that you're referring to. So, as it stands, it's impossible to answer your question.
The AnswerBank is UK-based. In this country the educational year is divided into three terms, rather than four quarters. Further, although there are, of course, grades for externally-set examinations, there's no common grading system used by schools, colleges or universities. So people here simply won't know what it is that you're referring to.
My guess is that you're in the USA. If so, I suggest posting your question on a US-based forum, such as Quora. If you're elsewhere in the world (such as India, as we seem to get lots of question in the 'Jobs & Education' from there), I suggest seeking out a local forum for your particular country.
Returning to the possibility that you're posting from the USA, this
might then help although, as it shows that different systems are used by different schools and colleges, you might still not get a definitive answer. (Sorry!)
