  1. EVALUATIONPLAN:

    1. The course will be evaluated in three components: Continuous evaluation, Mid-term and End-sem tests.

The weightage for the three components is as follows:

Continuous Evaluation : 25 Marks Mid – Term Exam : 25 Marks End- Term Exam : 50 Marks

2.Continuous evaluation will include thefollowing

  1. After completion of all 10 experiments, a written quiz Test will be conducted for 20 marks, Time: 45 Minutes.

  2. Record book will be checked after each experiment. At the end of semester, record willbe

evaluated for 5 marks for neatness and completeness.

  1. Total continuous evaluation component is 20+5 = 25Marks

d)Quiz Test will be a common test for all 1st year B Techsections.

 

  1. Mid-term exam will have a weightage of 25 Marks. ONE procedure writing (only procedure for 10 minutes duration) for 5 marks and ONE experiment for 20 marks (from volumetricpart).

  2. End-Term Test will have a weightage of 50 Marks. ONE procedure with calculation steps (in 15 minutes) either from either volumetric titration or instrumentalexperiment.

  3. Two experiments one from volumetric (only one titration) and another from instrumental part for 20 Marks each. (20 +20Marks).
