Here's a chance to practice with percentages and learn how to calculate your grade at the same time. Suppose your final score in this course is determined by the following components and percentages:

Exam$120\%$

Exam$220\%$

Final $30\%$

Assignments $15\%$

Participation $5\%$

Lab $10\%$

In calculating the contribution from each part, multiply the fraction for that part by the percentage that part contributes to the grade. For example, if you scored $75\%$ on Exam $1,$ multiple $20\%$ by $0\mathrm{.}75.$ The result is a total of $15$ percentage points from Exam $1$ towards your overall percentage.

Suppose you have the following scores: $69$ out of $100$ on exam$1,74$ out of $100$ on exam$2,73$ out of $100$ on the final, $177$ out of $189$ points for LONCAPA assignments, $100\%$ for participation, and $94$ out of $100$ for lab. What is your final score for the class? Provide the overall score for the course as a percentage and don't forget to enter the percent sign.
