BIOL 230: Physiology Lab Exemption Instructions

A lab exemption will only be granted in the following cases. Lab exemptions for BIOL 230* may be granted if:

  1. an equivalent physiology course has been taken at a recognized institution.
  2. the course has been taken within the last 5 years.
  3. the student achieved greater than 50% on the lab component.

These criteria must be supported by an official transcript that shows a separate grade for the "equivalent laboratory component" of the course. If the lab mark is not shown as a separate mark on the official transcript, then you must arrange to send a "Lab Exemption Request Letter" from the lab coordinator at the previously attended institution to the Course Coordinator (

Once you are lab exempted there is a course mark redistribution so that your final mark is determined only by course work done with Athabasca University. For more details on the course mark redistribution, please see below.

The physiology lab exemption request information should be directly sent to the Course Coordinator (

*BIOL 230 Lab exemption information must be received BEFORE the course contract end date.

The final grade for the course cannot be processed until the official transcript has been received by Athabasca University.
