Dear Sudip, please don\'t try to mesh with your faculties at least. Yes, it will be a year lack if you are not able to clear your labs too. But, your teacher is also a human and he or she will never want that you fail due to him. So, if possible try to manage this issue with the concern faculty or tell about this issue to any other faculty who knows you a lot. Don\'t take tension and say \"ALL IS WELL\". :)
