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
