If you think grades is the sole factor in getting a job i do feel bad for you.. If you get called in for an intervju you have done the hardest part, an intervju is only for you to tell them why you want the job why you are qualafied and for them to see your personality. Your average grade could be an A but your absence from school is High therefor they wont hire you and you wont get called in for an intervju. The main reason why companies want to hire employees is to make a profit of them and if they see that your absence is High so they figure that you wont be at work enough for them to make a profit of you.
