A textbook is not a course, and a course nobody recognises is not a credential. Each part of this does the job it is actually good at.
1
The source
Wiley
Written by practitioners, vetted by editors
Every course starts from a published Wiley title — material that has already survived professional review, technical editing and years of readers who would have complained if it were wrong.

The transformation
Sejal Learning Systems
Turned from a book into a course you can finish
Reading a reference text is not learning. We rebuild each title around measurable objectives — short video, worked examples, practice with real feedback, and a project that produces something you can show.

The destination
Coursera
Studied and credentialled where employers look
Courses run on Coursera, so your progress, certificate and specialization sit on a platform hiring managers already know how to read.
