Ok, I think it was fairly similar then. Assignments were graded automatically (based on passing test suites essentially) but individual labs hadn't been set up the same way. With style I always felt it was easy to say if it was bad or good, but hard to justify sometimes; 'good style' often just means 'I can follow this easily as I read it' and that becomes subjective based on how you like to read code. Even so, it was always obvious when a student had spent time on their program, and gone back over the code to rewrite or clean it up - those tended to get the good style marks.
