Comidoc Review

Our Verdict

Designed for both beginners and experienced learners, this course thoroughly covers P&ID symbols while providing illustrative graphics. However, it falls short in offering practical tracing examples across multiple diagrams and addressing essential industry standards. The course's true value lies in its engaging teaching style, detailed lessons, and enhancement through visual aids.

What We Liked

The course effectively balances depth of content with accessibility, catering to both beginners and those with prior experience.
Detailed lessons that delve into the nuances of P&IDs, providing a comprehensive understanding of these complex diagrams.
Visual cues and aids greatly enhance the learning experience, making it easier to grasp intricate details.
A clear and engaging teaching style ensures even the most complex concepts are easy to understand.

Potential Drawbacks

Lack of practical examples for tracing items from one P&ID to another, which is crucial in real-world applications.
Overemphasis on advanced process control and safety instrumented systems that could be condensed into separate courses.
Some errors in the slides that could detract from the overall learning experience.
Limited downloadable resources and lack of an index or glossary of terms.
