Ya possible. Moreover the grade threshold will be lowered like always. But there's no more "don't work hard, work smart". You actually have to work hard. And even if you don't achieve straight As, you have nothing to regret because you know that you've tried your best. But if you work so hard, the worst possible outcome for you should be more than satisfactory anyway because there's no way you won't achieve at least 5C. Good luck!
