  28. N/A is still correct! And for the people that are saying cheating is bad, not everyone is cheating some come on here to check their answers to make sure they are correct because they may be confused on something and they want help. My overall message is to MIND. YOUR. BUSINESS! Don't worry about what other people are doing, worry about your own education.
