In Chem 1B your final course grade is made up of 60% of your lecture grade and 40% of your lab grade. Your lab grade is composed of your report sheets, lab exams and seminar quizzes. Your lecture grade is composed of your lecture exams, final exams and quizzes (in class or through Canvas, as determined by the course lecturer).

Go look in the Chem 1B Lab Greensheet for the weight of each graded component for lab (35% report sheets, 35% lab exams, 30% lab quizzes). A student is trying to figure out his LAB percent. So far he has 86% in report sheets, 66% in the lab exam and 76% in quizzes. What is the students total lab % at this time rounded to two digits?

76%

Explanation:

The lab grade of the student is made of report sheets, lab exams and lab quizzes with different weights for each score. To find the lab grade we need to multiply each score with respective weight. He has 86% in the report sheet which has 35% weight, 66% in the lab exam which have 35% weight, and 76% in the quizzes which have 30% weight. The score will be:

86%*35% + 66%*35% + 76%*30% = 76%

His score for the lab grade will be 76%
