HOME ASSIGNMENT BOOKLET Semester: 1st Subject: Chemistry-I Tutor Marked Assignments (TMA) for Subject Code ________Part I ________Part II ________Part III For any enquiry, please contact Office or Call at 01733-250096 or Visit www.mornigpw.org or contact us at [email protected]. Dear Student, This booklet contains the home assignments for Subject Code _______________. Each course has three assignments per subject, which you need to complete and submit to your teacher in charge at three intervals during the semester. P lease note that, the internal assessment of 20% of the total assessment of this particular subject will be based on your performance in this assignment. In case you fail to submit the same, you will be awarded zero marks in Home Work component of the Internal Assessment in this particular subject. The assignments constitute the continuous component of the evaluation process and will be the basis of your evaluation for the concerned subject during the semester. Instructions for Formatting Your Assignments 1. You should specify clearly on the first page of all your assignment responses the course code, course title, assignment code, your state board roll number, name and address in the given format: ROLL NO. :.…………………………………. NAME : …………………………………. SEMESTER : ……………………………………. NAME OF DIPLOMA : ……………………. SUBJECT CODE : ………………………….. ASSIGNMENT : Part I ; Part II, Part III (Please tick) DATE : …………………………….….. PLEASE FOLLOW THE ABOVE FORMAT STRICTLY TO FACILITATE EVALUATION AND TO AVOID DELAY. 2. The Assignment Response should be hand-written and use only A-4 or foolscap size writing paper (but not of very thin variety) for writing your answers. 3. Leave at least 4 cm margin on the left, top and bottom of your answer sheet for the evaluator’s comments. 4. Your answers should be brief, precise and in your own words. Please do not copy the answers from the study material. 5. A serious action will be taken if any attempt to copy the Assignment Response from other student is done. 6. While answering the questions, clearly indicate the question number along with the part being answered. Recheck your work before submitting it. We recommend that you retain a copy of your assignment response to avoid any unforeseen situation. Submit your completed assignments to: TEACHER INCHARGE FOR THE SUBJECT Wishing you all good luck!
