Paragraph:

Use of Social Media During MDCAT

Social media plays a significant role during MDCAT preparation, offering both benefits and challenges for aspiring medical students. Platforms like YouTube, WhatsApp, and Instagram provide access to study resources, such as video lectures, practice questions, and peer discussion groups, enabling students to clarify concepts and stay motivated. However, excessive use of social media can lead to distractions, with entertainment content or notifications disrupting study schedules. To balance this, students should set specific times for using social media for educational purposes and avoid mindless scrolling. By using these platforms wisely, students can enhance their preparation while minimizing distractions.
