- Misconception: 'All ICT support is just fixing hardware.' Correction: While hardware repair is part of the role, much of the work involves software troubleshooting, network configuration, and user training. Soft skills are equally important.
- Misconception: 'You need to know everything about computers to pass.' Correction: The diploma focuses on practical, job-ready skills. You don't need to be an expert in every area; understanding core concepts and how to find solutions is more valuable.
- Misconception: 'Networking is too hard for beginners.' Correction: The Level 2 diploma introduces networking gradually, starting with basic concepts like IP addresses and cables. With hands-on practice, students can confidently set up and troubleshoot simple networks.
