Marko with UBC Chemistry 103 instructor Dr Richard Spratley, standing in the ramp which descends down into the lecture hall, just before the Christmas examination.  Marko blinked.

Students begin to assemble for the Christmas examination in Chemistry 103.  Marko can be seen holding up his hand on the upper left.

More students have assembled for the Christmas examination in Chemistry 103.  Marko is in the red-and-white striped shirt just left of center.

The Christmas examination in Chemistry 103 is about to begin.  Marko has been moving around the lecture hall demonstrating a magic trick involving an apparently impossible switching of an elastic from one set of fingers to another, and presently is still playing with the elastic.

Marko visits Dr Richard Spratley in his office later that same summer, and gets a good picture to make up for the one in which he blinked.

Chemistry 103, completed at age 10:07, while nominally in Grade 5, and earning the course grade of 80%

Below is the final examination for Chemistry 103 which, however, covers only the work from January to April, and so does not reflect the full scope of the September-to-April course.  The examination was spread over twelve pages, containing much blank space for the answers, which blank space has been cropped out below.  The relevant comparison is to Grade 5 students in conventional school, many of whom in Canada and the US are still struggling, not always successfully, to master multiplication and division, as is discussed at THE DECLINE OF MATHEMATICS EDUCATION IN AMERICA.

The TBT expectation of doing well on Grade 12 Chemistry at the age of 12 is considerably exceeded in this example, as it shows a student doing well on First-Year-University Chemistry at the age of 10:07.
