To calculate the average percentage for your tests, follow these steps:

1. List of marks:
   The marks you received on your tests are as follows:

   • 7, 12, 11, 15, 8, 23, 30
     Corresponding maximum marks are:
   • 12, 15, 40, 25, 10, 30, 50

2. Convert each mark to percentage:
   To find the percentage for each test, divide the mark by the maximum mark and multiply by 100.
   $\text{Percentage for test 1} = \left(\frac{7}{12}\right) \times 100 = 58.33\%$ $\text{Percentage for test 2} = \left(\frac{12}{15}\right) \times 100 = 80\%$ $\text{Percentage for test 3} = \left(\frac{11}{40}\right) \times 100 = 27.5\%$ $\text{Percentage for test 4} = \left(\frac{15}{25}\right) \times 100 = 60\%$ $\text{Percentage for test 5} = \left(\frac{8}{10}\right) \times 100 = 80\%$ $\text{Percentage for test 6} = \left(\frac{23}{30}\right) \times 100 = 76.67\%$ $\text{Percentage for test 7} = \left(\frac{30}{50}\right) \times 100 = 60\%$

3. Find the average percentage:
   Now, sum all the percentages and divide by the number of tests. $\text{Average percentage} = \frac{58.33 + 80 + 27.5 + 60 + 80 + 76.67 + 60}{7} = \frac{442.5}{7} = 63.21\%$

So, your average percentage for the tests this term is approximately 63.21%.

Tip: To calculate averages quickly, always ensure you are dividing by the number of tests or subjects you are considering, and consider weighted averages if some tests are more important than others.
