The introduction of new subjects or changes in the weightage assigned to various components, such as prelims or mains, can impact candidates' preparation strategies. Staying updated with official notifications regarding recruitment patterns and understanding the competitive landscape is essential for aspirants to adjust their study plans and optimize their efforts accordingly.
