The education system prioritizes that all students have a baseline knowledge above all else. It's not the goal to incentivize high achievers using a hard scoring system, because this'll prevent the success of others who aren't good in educational settings - and there is a group of people who are incredible programmers, but lack the skills to get good grades.

If you're really good, you have remarkably good grades and do interesting projects in your spare time. w.r.t. your understanding of unfair: Don't compare yourself to fellow students, because they are by definition average. If you want to profit from your advantage: do stuff, get connected with great minds, build projects. This will get you years ahead of your fellow students who are busy passing the exams. What about this incredibly unfair advantage? ;)
