Every optional has a “cut-off” mark. Hence, is it better to choose one with a low “cut-off”?

What is the meaning of cut off? Only 10000 qualify at the preliminary. The marks scored by the last candidate is the cut-off. Thus all candidates who score more than the cut-off will qualify and those who don’t will not. This is a competitive examination. There is no qualifying score. Whatever the marks are, the first 10,000 ( this figure also subject to change – depends on number of vacancies) candidates will qualify. Thus, cut – off mark changes from year to year. If the questions are difficult the “cut – off” automatically comes down.
