Critics have also stated that the computer-adaptive method of placing more weight on the first several questions is biased against test takers who typically perform poorly at the beginning of a test due to stress or confusion before becoming more comfortable as the exam continues.  On the other hand, standard fixed-form tests could equally be said to be "biased" against students with less testing stamina since they would need to be approximately twice the length of an equivalent computer adaptive test to obtain a similar level of precision. 
Since the turn of the new century, a theory has emerged concerning the end of the world, or at least the end of life as we know it. This new theory centers around the year 2012, a date that many claim has mysterious origins in ancient manuscripts from many different cultures. The most noted characteristic of this date is that it appears to mark the end of the Mayan calendar. But there is no evidence to suggest that the Maya saw any great relevance to this date. In fact, none of the claims surrounding a 2012 doomsday event hold up to scientific inquiry. The year 2012 will pass without a major, life-altering catastrophe .
