CSCI 1133 Final

Does anyone know how exactly the CSCI final is graded? Like I know that it’s counted as two quizzes, but I’m not sure how exactly it goes or if there are sections, because I need like a 38/50 on bit quizzes to go to a B+ or I can get a 45/50 on one of the quizzes so that it replaces the lowest score on one of my quizzes and drop the other one. Like is it graded in a way that if I get 60/100 I get a 50/50 and a 10/50 or are there like sections for each quiz, because I heard that the final is 3 quizzes long.
