Can someone figure out this calculation?

This semester is almost over and I want to know what I have to get on tomorrows final exam to make a B or C in the class. I dont know how to add them up. It will be very much appreciated if someone could help me calculate. Please and thank you very much! I take human anatomy 1 plus the lab… A class lecture and a lab.

Class lecture= 400 pts.

Lab= 300 pts.

Here are my grades on the tests for the lecture class….

74%

86%

76%

Here are my grades for lab.

There are 10 quizzes we took which are worth 100 pts. all together

I got 100 on all of them except two. I got a 4 out of 10 for one and 6 out of 10 for the other. I failed those two.

Final exam for lab I got a 69%

So what would I have to get on the final exam tomorrow to get a B in the class?

Here is what my syllabus says:

The final grade will be determined by:

1. Lecture average (400pts)

2. Lab average (300pts.) There will be two Lab Practical exams. There are NO

Lab Practical Make-up Exams. There will also be lab quizzes that will

account for a total of 100 pts.

For the overall course, your score out of a total 700 possible points will be converted to a percentage and you will receive that letter grade corresponding to the following scale:

A = 90 - 100%

B = 80 - 89%

C = 70 - 79%

D = 60 - 69%.

F = under 59%

F-nonattendance: students who enroll in the class but fail to attend labs/lectures and exams will receive a grade of F-nonattendance.
