Note:
MSQ – multiple choice/select question – This kind of question normally has 4 options and the correct answer is 1only. There is also Yes/No type answering questions.Invalid HTML tag: tag name o:p is not allowed
Comprehension question [SA – Numeric] Type:Invalid HTML tag: tag name o:p is not allowed
This comprises a problem/passage and based on this there are sub questions. Hence if asking to solve a problem, since in online evaluation, the student can lose or get marks based on just the final answer and does not get any step marks, we suggest these be created as comprehension questions (maybe 3 or 5 sub questions) where the formula or intermediate answers can also be asked and marks given if he/she is correct till that. Sub questions are SA – Numeric type. Invalid HTML tag: tag name o:p is not allowed
SA – Numeric: This is a fill in the blank question. Answer to be entered is numeric. (0-9 and decimal point are allowed to be entered). Answer can be matched against an exact value or a range can be specified for the answer within which if entered value falls, it will be marked correct. In the question the correct units have to be mentioned for the answer entered. Range is preferred as opposed to Exact value to allow for approximations.Invalid HTML tag: tag name o:p is not allowed
The time required for answering a question may not be proportionate to the mark assigned. This is because you have to solve numerically a part or full of a problem given. Then answering (mostly fill in the blanks) questions will take very little time. Also please note that:Invalid HTML tag: tag name o:p is not allowed
(i) Units are given in the question or answer line. Please take care of the unit while you are solving.Invalid HTML tag: tag name o:p is not allowed
(ii) You would also take care of sign. For an example a force or a moment may be negative or positive. Similarly the transmission ration may be negative or positive (depends on input/output directions).Invalid HTML tag: tag name o:p is not allowed
(iii) In fill in the blank a range i.e., + - of exact value is given (you will not see it). If your answer falls within this range your score will be full. A moderate range has been assigned for all questions.Invalid HTML tag: tag name o:p is not allowed
