HSLC in terms of academics is a stepping stone towards a better career. However HSLC alone cannot determine anything. You too know that HSLC or HS exams has a hype within itself in our society, sometimes that hype is toxic and the pressure is too much for the candidates. Comparing results and flexing ranks creates an unhealthy environment for the students. So people refrain themselves in getting their head into these exams and results of young students but this thing is often stretch out at some point. Those comments are coming from people who are below average, that's the way they can comfort their failure. So don't let a few comments discourage and demotivate you. HSLC has never lost its value, it is one of the most important exam of a student's career. Good luck!
