It is almost always better that a particular country's education system be as flexible and be as accessible to as many different people as possible, than to have a particular country's education system be very rigid and very restrictive.
The education system in a lot of countries around the world tend to be very elitist and very prohibitive - they only want the top percentage of students in the country to have the opportunity to be able to study in higher educational institutions, such as a college or a university, to obtain both undergraduate and postgraduate degrees and qualifications.
However, such highly rigid and highly restrictive education systems in a lot of countries around the world are greatly flawed as they are defeating the real and true purpose of education, which is to give as many different people in a country the opportunity to get a good education for themselves in life.
The true objective of education in any country in the world is NOT to be very competitive in an academic environment and compete against other people to find out who is smarter, more hard working, more knowledgeable/ skilful/ experienced, more creative/ innovative, more focused, more determined, more successful, etc, in life.
The true goal of education in any country in the world is to ideally provide an avenue and an outlet for people to learn whatever that they want to or like to learn in life, to train them in a very specialized field of study, and to impart very important and very valuable knowledge, skills, and experiences to them, so as to be able to help a lot of different people to be able to secure employment and good jobs that allow them to make a good living and subsequently be able to support themselves and their families.
Education is not about competing with other people and beating each other in many different academic tests and exams, to see who has better and higher test scores, academic grades, and exam performances.
Education is supposed to turn people into even better people, who have been specifically trained to have much more well-developed, much more cultured, much more civilized, and much more sophisticated mentalities, characters, personalities, etc.
