Solution:

To calculate his average, we need to get the sum of marks on his tests, then multiply it by number of tests.

$\displaystyle \small \tt Average = \frac{Sum \ of \ marks \ on\ tests}{Number \ of \ tests} \\\ \\ \tt Avg = \frac{75 + 72+63}{3} \\\\ \tt \: Avg = \frac{210}{3} \\\\ \: \tt{Avg = \underline{ \boxed{ \blue{ \bold{70}}}}}$

Hence, his average is 70.
