QR101 is the new CS102 

As of the 2014-15 school year, Math 055 and CS102 have been discontinued.  A new course, QR101 - Foundations in Quantitative Reasoning, replaces these courses.  Unlike its predecessors, QR101 is a four-credit course and has a prerequisite of 30% on the ALEKS placement exam.  

Consult the College Catalog for those courses requiring the proficiency prerequisite “CS102 or Math 055 or equivalent”, which will now be fulfilled by your successfully completing QR101.

QR101: Foundations in Quantitative Reasoning
Students will learn how to apply elementary mathematics, statistics, and algebra to quantitatively analyze, model, and solve problems in authentic contexts with a focus on effectively reporting the results and conclusions.  Topics include units, dimensional analysis, estimation, percent change, proportional reasoning, linear and exponential modeling, systems of equations, charts and graphs, descriptive statistics, logarithms and logarithmic scale, linear regression, correlation, and what-if analysis.  Emphasis on using computational tools such as graphing calculators and Microsoft Excel appropriately and effectively.   

What is “QR101 or equivalent”?

The prerequisite “QR101 or equivalent” means meeting ONE of these criteria:

  • receiving a score of 4 or 5 on an AP exam in Calculus AB or BC, 
  • receiving a score of 5, 6, or 7 on an International Baccalaureate standard or higher level mathematics exam;
  • successfully completing CS102 or QR101 
  • achieving a score over 53% on the ALEKS placement exam
