If you study hard will pass?

It is not guaranteed that you will pass if you study hard. While studying hard can increase your chances of success, there are many other factors that can affect your performance and outcome, such as the difficulty of the material, your learning style, your level of motivation, and external circumstances. However, studying hard can help you build a strong foundation of knowledge and skills, develop good study habits, and increase your confidence, all of which can contribute to your success in passing an exam or achieving your academic goals.
