ALEKS Maths Placement Exam

<p>So, I got admitted to Penn State (University Park) Fall 2014 for MechEng. I have to give this ALEKS Maths Placement Exam. Anyone else giving the exam who is attending Penn State?? Or has anyone else given the exam?? How tough is it?? Tougher than CBSE Maths?? I would also appreciate the opinions of my fellow seniors who have already given this exam. Also, do we have to give this exam at home??</p>
