If you have purchased or are considering purchase of one or more registrations for the CETP 4.1 - Designing and Installing Exterior Vapor Distribution Systems Class non-accelerated, live, online, instructor-led, interactive class,  a summary of what you need to know is contained herein.  You may have already seen this on the store class description, or Mike Digiorgio or Shane Sweet  may have emailed it to you.


Preparation - Students and those registering students:  You must read this entire document and be prepared for class.   Regretfully, time constraints do not allow for accommodation of significant disruption or delays in class to assist individual students arriving for class without preparation.  Consider:   

  • failure to secure the required publications and have them ready for use in class.  Implications:  we cannot spend significant time during class assisting students with retrieving the supplied .pdf of the book or books.

  • failure to test your computer equipment and ensure its working order before class begins.  Implications:  The entire class relies on every student showing for class with his or her equipment ready to use.  We cannot spend class time addressing technical issues for individual students.

  • failure to have a PERC account set up before class -  with delay of exams resulting.  Implications:  Secure your individual PERC account before class.  Arrive for class with this already done.  We cannot spend class time addressing this for individual students.

  • failure to have a working camera and working microphone as class begins. Implications:  Camera and microphone and speakers/headset are essential to participate in class.

  • Use a Desktop computer, Laptop computer or Tablet.   We do not recommend the use of a Smartphone for general class sessions.

We reserve the right to release from class any student showing for class but not clearly not prepared to participate without delay.  In that event, the student and company will forfeit the fees for that class.
