Calculation-1
Objective :
To test calculation skill of the candidate
Question:
Calculate the amount of potassium permanganate required to prepare 50 ml of 2% potassium permanganate.
![Page 25: Objective Structured Practical Examination (OSPE)](https://reader033.vdocuments.us/reader033/viewer/2022061409/56814380550346895daffdfd/html5/thumbnails/25.jpg)
Calculation-2
Calculation:
2% means 20 mg/ ml solution
[1 % 10 mg/ ml]
Hence 50 ml of 2 % solution requires solute=
50 ml *20 mg/ ml
=1000 mg
![Page 26: Objective Structured Practical Examination (OSPE)](https://reader033.vdocuments.us/reader033/viewer/2022061409/56814380550346895daffdfd/html5/thumbnails/26.jpg)

OSPE - Advantages
1. Minimum bias 2. Uniform level of assessment3. Large number of skills can be assessed objectively4. Wider sampling-most topics can be covered4. Reliable method of testing5. Tailor made assessment of skills as per importance6. Minimum subjectivity7. Recall bias minimised
![Page 31: Objective Structured Practical Examination (OSPE)](https://reader033.vdocuments.us/reader033/viewer/2022061409/56814380550346895daffdfd/html5/thumbnails/31.jpg)
OSPE - Disadvantages
1. Standard time duration for all- can’t be /
2. Requires planning
3. Requires validation
4. Requires team work
