Campus placement preparation requires consistent practice in quantitative aptitude, logical reasoning, and analytical problem-solving. Traditional preparation methods often lack structure, performance tracking, and real-time feedback, making it difficult for students to evaluate their progress effectively. This paper presents the design and development of an Aptitude Portal integrated with an Android Application, aimed at providing a centralized and interactive platform for aptitude preparation. This system categorizes questions topic-wise and difficulty-wise (Easy, Medium, Hard), enabling progressive learning. It includes time- based quizzes, instant score evaluation, streak tracking, and performance monitoring to encourage consistent practice. The admin panel allows dynamic management of questions using Firebase Firestore, ensuring that content remains updated and relevant. The web application is built using Node.js, Express.js and EJS, while the Android app is developed using Kotlin and XML. By integrating web and mobile access, the system ensures flexibility, accessibility, and scalability. The proposed system enhances student engagement, supports self-assessment, and improves placement readiness through structured and gamified learning.
