We would like to inform everybody that Mathizen is developing a scoring system of our users' Math Proficiency that is uniquely Mathizen. Programming and testing of the new scoring system is on-going. Please do not be surprised of the frequent changes in your rank and scores. Because of this new system of scoring and ranking, We enjoin our users to correctly update their profiles' age, birthday and grade level as these are factors in computing the scores or points earned. We are doing this in preparation for a contest next year. PLS. UPDATE CORRECTLY YOUR PROFILES NOW.
