if i have a overall grad of 99% and I got a 0 on a portfolio that weighs 33%, what grade do I get?

If the portfolio weighed 33% of your overall grade and you received a 0 on it, then your grade for that component would be 0.

To calculate your overall grade without the portfolio, you would multiply your overall grade (99%) by 67% (100% - 33% for the portfolio).

0.99 x 0.67 = 0.6633

So your overall grade without the portfolio would be 66.33%.

what is my semester grade after i get that 0?

If your overall grade without the portfolio is 66.33% and the portfolio weighs 33% of your overall grade, you would calculate your semester grade with the following steps:

1. Multiply your overall grade without the portfolio by 67% (100% - 33% for the portfolio weight):
0.6633 x 0.67 = 0.444911

2. Since the portfolio weighed 33% and you received a 0 on it, your grade for that component is 0.

3. Add the result from step 1 to the grade for the portfolio:
0.444911 + 0 = 0.444911

Therefore, your semester grade after receiving a 0 on the portfolio would be 44.49%.

my overall semester grade is 99 percent

If your overall semester grade is 99% and you received a 0 on the portfolio that weighs 33%, then we can calculate the impact of the 0 on your overall grade with the following steps:

1. Calculate the overall grade without the portfolio:
Let x be the overall grade without the portfolio.
x * 67% (weight of overall grade without the portfolio) = 99%
0.67x = 99
x = 99 / 0.67
x = 147.7612

2. Since the portfolio is worth 33% of the overall grade, the impact of the 0 on the portfolio would be:
147.7612 * 0.33 = 48.766

3. Subtract the impact from step 2 from your overall semester grade:
99 - 48.766 = 50.234

Therefore, your semester grade after receiving a 0 on the portfolio would be approximately 50.23%.
