How does WelCOM work?
Unlike traditional examinations that give you a one-time snapshot of your performance and/or answer keys after you’ve completed the exam, WelCOM gives you an answer and rationale after each question and uses an easy-to-read review panel that provides real-time progress to help you close the gaps in your knowledge.
WelCOM is also convenient, accessible 24/7 on your smartphone, tablet, desktop, or the CATALYST app. It’s customizable; you can answer one question or as many as you like on your own time. You will have 180 days to complete the assessment after your first login to the CATALYST platform after purchase. You can go back in and review your answers and rationales as many times as you like for that duration of time.
