passes = passes + 1;failures = failures + 1;studentCounter = studentCounter + 1;

with prefix increment operators as

++passes;++failures;++studentCounter;

or with postfix increment operators as

passes++;failures++;studentCounter++;

When incrementing or decrementing a variable in a statement ...
