ISM wants more students with entrepreneurial mind-set in the next batch. To achieve this, ISM is considering following proposals:
I. Preparing a question paper of two parts, Parts A and Part B of duration of one hour each. Part A and Part B would consist of formula-based problems and application-based problems, respectively. After taking away Part A, Part B would be distributed. The qualifying cut-off percentile would be calculated on the combined scores of two parts.
II. Preparing a question paper comprising Part A and Part B. While Part A would comprise formula-based problems, Part B would comprise application-based problems, each having a separate qualifying cut-off percentile.
III. Assigning one mark for formula-based problems and two marks for application-based problems as an incentive for attempting application-based problems.
IV. Allotting one mark for formula-based problems and three marks for application-based problems, without mentioning this in the question paper.
Which of the following proposal (or combination of proposals) is likely to identify students with best entrepreneurial mind-set?
