Certainty Based Marking (CBM) is a way for students to reflect on their "confidence" and "bet" on their answers to help reflect on their understanding, and has been scientifically proven to be a more accurate measurement and reflection of a student's understanding!
Scores are scaled to be based on accuracy with a "CBM Bonus" based on how well students "bet" on their confidence, and a CBM Report is given to each student after an attempt to help them reflect on their understanding--turns even True / False questions into a better measurement of student understanding since it's not just a 50/50 proposition!

Invented by the brilliant Dr. Tony Gardner-Medwin, emeritus professor of physiology at University College London, with a background in biophysics, computational and experimental neuroscience to help prepare his students for the rigors of medicine and neurosurgeries where simple guessing can be a matter of life and death!
