School schedule goes as it follows:
8:15 starts classes. As the first class is Math.
9:00 is the first 10-minute break.
9:10 starts second class: Spanish.
9:55 is the second 10-minute break.
10:05 starts third class, which is History.
10:50 is the third 10-minute break.
11:00 starts fourth class: Chemistry.
Therefore it is correct to say that:
- <em><u>Mi clase de matemáticas es a las 8:15</u></em> ("My Math class is at 8:15").
- <em><u>Mi clase de español es a las 9:10</u></em> ("My Spanish class is at 9:10").
- <u><em>Mi clase de historia es a las 10:05 </em></u>("My History class is at 10:05").
- <u><em>Mi clase de química es a las 11</em></u> ("My Chemistry class is at 11").
