Are You Smarter Than A 5th Grader? (UP)

In order to unlock this achievement you'll have to answer all the questions on your own in one playthrough. As in you can't use any of the three cheats to help you answer a question. When the credits roll after each playthrough this is where you'll see the award for "Independent Student" if you did it correctly. This achievement can be done solo in "Exam" mode, and in "Study" mode with 1-2 players. ["Study" mode with 3-8 players will activate modifiers in which group answers do not count towards this achievement. You'll receive the award "Wise Leader" instead of "Independent Student".]

An easy way to grind this achievement out is to play "Exam" mode, and answer the first three questions correctly on your own. Then during the second question of 2nd grade you can get that question wrong, and "Independent Student" will always pop up as an award during the credits.
