Campus recruitment math tests often present a significant challenge for students, especially those with limited confidence in their practical math skills. However, with the rise of online learning platforms, finding effective resources has never been easier. YouTube offers a wealth of simple and accessible videos that focus on applied mathematics concepts like percentages, ratios, and proportions. These can help K12 students and job seekers build confidence and perform well under pressure.
Whether you’re preparing for a technical interview or tackling a general aptitude test, YouTube channels provide step-by-step tutorials that simplify complex topics. In this article, we explore some of the best resources available and offer tips for using them effectively to master applied mathematics.
Why Applied Mathematics Matters in Campus Recruitment
Applied mathematics—the use of mathematical concepts in real-world scenarios—plays a vital role in campus recruitment tests. Companies often assess candidates’ ability to solve problems related to financial calculations, data interpretation, and logical reasoning. Concepts like percentages, ratios, and proportions form the foundation of many test questions.
For example, calculating growth rates, understanding budget allocations, or analyzing trends requires fundamental knowledge of percentages and ratios. In addition, proportions help candidates solve challenges involving scaling or comparing values across different datasets. Fortunately, YouTube is packed with practical lessons tailored to these topics.
