The Concept Notes are featuring vector graphics and document cross-links: Thus, test the link at the bottom of page 1 …” skip ahead to page 85, “… – whether it redirects to this page indeed!
Unfortunately, PDF-viewer like Acrobat Reader or Google’s “Drive PDF Viewer” or even Apple’s Preview are not state of the art.
All Chrome-browser derivatives, e.g. Edge are perfect for viewing and printing. Otherwise ReadEra is correctly rendering in Android OS as well as Sumatra in Windows OS – both for free!
In any case it is highly recommended to first download the file(s).
Update: The Permanent Secretary of the Tanzanian Vice President’s office “is commending” to the ETEC concept.
