RULES & REGULATIONS FOR LABORATORY 1. Before entering into the lab, be sure that your shoes are on the rack. 2. No late comers are allowed (except medical case with a valid reason). 3. Put your signature first, submit the record and then go to your place. 4. Handlings of other things which are not related to the experiment are strictly prohibited inside the lab. 5. You may be charged with full cost and additional penalty for destroying the equipments. 6. You should come with formal dress and Identity card, otherwise you will not allow. 7. Till the time you are inside the lab you should stick to your place and don’t move here & there. 8. Before leaving the lab, be sure that the computer is turn off, return the kit and other components to the Lab Instructor otherwise the entire group members will suffer. 9. Your rough copy and output must be verified by any one of the instructors present in LAB else your experiment will not be considered in the next lab class. 10. You yourself will be responsible for exchange or missing of any precious materials. 11. You can demand for marks on the basis of performance ONLY, but can’t beg. 12. No extra lab for the experiments. Extra labs may be allowed for serious medical issues on your request if your application is forwarded through proper channel within the time limit. Beyond the time limit it is never accepted at any situation. NATIONAL INSTITUTE OF SCIENCE AND TECHNOLOGY PAGE iii
