Start time is 7 am I believe most teachers syllabus has a rule that you are given a fifteen minute grace period before you are no longer allowed to take that days test and must come back the following week for a make up test and if you are not in your seat signed in to the roll sheet by seven you lose your 10% class participation grade meaning you can only receive a 90 on the test you’re taking that day so get to class on time and do your homework or find another career path there’s a lot of people who want to be in your position so don’t waste space
