By Sidney Edward Martin on 9/9/2026

The course is a good match. I know specific aspects of the P&ID well. But, I have not ever taken a course that walks through the P&ID development process.

By Hadj Djillali Messaoudi on 9/4/2026

Yes, this course seems ideal for a safety and health engineer like me. It provides the opportunity to comprehend P&IDs and grasp how process control functions.

By Brady Hanas on 5/29/2026

This was a good course that clearly walks you through how to understand and interpret a P&ID. It provides a solid foundation for anyone looking to build or refresh their skills in reading piping and instrumentation diagrams.

By Anton Boykov Temelkov on 4/22/2026

So far, so good. Whenever you introduce new concepts, explain what they mean (and repeat them a few times)—this helps with retention. When listing various documents, show images or references to help students orient themselves better, and specify whether they will be covered later. This way, you avoid interrupting the course for quick Googling.

By Manuel Biasion on 1/14/2026

I would like a more detalied and consistent practice section. For example, the course focus a lot on SIS but there are not examples where a SIF appear. Also more complicated P&ID would be great.

By Avil Kumar Shetty on 1/8/2026

This course provides a well‑structured and practical introduction to Piping & Instrumentation Diagrams (P&IDs). The concepts are explained clearly, making it easy to understand symbols, line identification, instrumentation details, and control philosophies commonly used in industrial projects.

By Avtar Ahluwalia on 12/25/2025

Yes, the introduction was good, narration is clear and at a speed which people from diversified backgrounds can easily understand especially people whose first language is not English. Content is very well organized.

By Rachit Kotian on 12/10/2025

I recently completed course and found it to be a clear, practical, and well-structured introduction to the subject. Further P&ID examples and small project work would have been more interactive.

By Cristian Pastenes Uribe on 11/26/2025

He logrado llegar a la mitad de la sección 13. El expositor se escucha muy preparado y me sorprende la cantidad de información que posee el curso. En realidad, no esperaba obtener tanto por el precio del curso. Me encuentro bastante satisfecho.

By Adel Showaya on 10/29/2025

Good intro to P&IDs for beginners, but it focuses more on instrumentation than piping or tools. The lecturer sounds like he’s reading from a script, and the voice feels artificial. Not bad overall, but it needs more practical examples and a more natural teaching style
