Scheme of Examination

The duration of examination will be 4 hrs.

The following exercises will be set in the examination

1. Sample Analysis:

The students will be allotted two samples for quality testing (Five marks each).

Five marks shall be further divided as-

Two marks will be awarded to a candidate if she has approached in a systematic and correct manner towards the testing of samples and three marks will be awarded for each test correctly reported and properly recorded.

2.Quantitative Analysis:

The exercise carries 25 marks. The distribution of marks will be as follows:

Five marks will be reserved for the preparation of solutions, neat methodical and systematic working of the candidate.

The remaining 20 marks will be distributed as follows:

• Theory                                                        3 marks
• Correct observation and proper recording     3 marks
• Use of correct formula and calculation          4 marks
• Result                                                         10 marks

3.Preparation:

The exercise amongst the candidates will be allotted by lot. Preparation of the product carries 15 marks. Five marks out of 15 are reserved for neat, methodical and systematic working. The yield, purity and proper presentation of the product shall be taken into account while awarding marks.

4.Viva:

Oral questions shall generally be asked over the work assigned to the candidate.

The semester end examination paper would be set by the internal examiner. The mode of examination would be both practical as well as theory. The candidates are expected to write both theory and practical component compulsorily in examination answer sheet.
