HELP PLEASE!!! Easy 10 Pts!!!?

I had an 83.3 in Science on my interim. Since then I've made a 85,91, and 64 on quizzes adn a 100 and 93 on tests. I dont know what percentage my teacher counts tests or quizzes but i just want to know if you all think my overall average will come out to a low B because tests are worth wayyy more than quizzes but i'm just not sure
