## MCR 3 - Learning Support for Technical Mathematics at New River Community College

### Course Description

Effective: 2017-08-01

Provides mathematical instruction for students who require minimum preparation for college-level but still need further preparation to succeed. Students in this course will be co-enrolled in college-level Technical Mathematics. Credits not applicable toward graduation and do not replace MTE courses waived. Successful completion of Technical Mathematics results in the prerequisite MTE modules being satisfied.

Lecture 1-2 hours. Total 1-2 hours per week.

1-2 credits

### General Course Purpose

To enable qualified students to enter into credit bearing courses sooner, with the appropriate support, and with equal or better success than those students meeting course prerequisite requirements. The course provides support and enhancement of foundational and course content required of the credit course.

### Course Prerequisites/Corequisites

Prerequisites: Completion of any four of the MTE units 1-6. Corequisite: MTH 131.
