Re: True or false?

Why not give the other questions a go? If you’re not sure, you can always guess. Then instead of telling you the answers, I can tell you how many you got right. After enough people have tried, I’ll post all the answers (if no-one has got them all yet).

Re: True or false?

Since me and ganesh answered two of the questions differently, doesn't that mean our scores should have the same parity?
