On December 5th Mr. Andy gave his 1B class a physics test that was much more difficult than the test received by his other periods. On December 7th it was discovered that Mr. Andy had accidentally taught and assigned his 1B class AP Physics material, even though they were not taking an AP physics class. Upon discovering this Mr.Andy cancelled the first test and allowed his 1B class to retake the test. This kind of simple mistake is costly and is easily avoided. Teachers are encouraged to double check assigned work as this kind of mistake can severely impact students.
