The IES vacancies significantly influence the IES cutoff. The number of vacancies directly impacts the cutoff as it affects the competition level among candidates. A higher number of vacancies can lead to a lower cutoff, allowing more candidates to qualify for the next stage of the examination. Conversely, a lower number of vacancies results in a higher cutoff, making it more challenging for candidates to meet the minimum qualifying marks.Additionally, the availability of vacancies across different engineering branches plays a crucial role in determining the cutoff for each category and discipline. Therefore, understanding the number of vacancies and their distribution is essential for candidates to gauge the expected cutoff and strategize their preparation accordingly
