Pleаse be аwаre that it is difficult tо prоgram answers fоr every possible calculation variation that the students may offer while still being "correct." For example, the exact answer rounded to three decimal places may be 0.781. Students may still work the problem correctly, but round in their steps. They may get 0.782 or 0.780 etc.... There may also be typos and spelling errors. For these reasons, correct answers may be marked as incorrect initially. I do review the tests and try to correct these errors. Don't panic until I have reviewed the tests.
