Two comic books have been prepared by CBSE and released.
One book explains what are critical thinking skills (Cogito) and the other explains what are problem solving skills (the question book)
Both comics are released as student resource material for PISA.
I highly recommend all states to reach these comics to all their students in classes 8 to 12, These 21st century skills are essential for all our learners.
