Text Entry:

  • Make sure your spelling is correct. Incorrectly spelled answers will always be graded incorrect.

Equation Entry (Chemistry):

  • If there are rules about the case of letters in your answer, make sure your answer is capitalized correctly. (For example, "CO" is carbon monoxide, which is not the same thing as "Co" cobalt.)
  • Make sure you follow subscript and superscript rules. (For example, when written correctly, the formula for water should appear as H2not H2O.)
  • Make sure you have not used zero in place of an "o" or vice-verse. (For example, when written correctly, the formula for water should appear as H2not H20.)

Equation Entry (Math):

  • Answers are case-sensitive. For example, "A" will be graded differently than "a".
  • If there are multiple terms in the denominator of a fraction, you may need to enclose the entire denominator in parentheses. For example x/(y+z) is not the same as x/y+z. Alternatively, you can omit the parentheses by using a stacked fraction.
