I partially agree. The onus is always on the indivdual. An organized class can provide comraderie, a place to ask questions, guidance, and many other benefits. But in the end, it is always up to the individual to get something out of it. A determined person with some basic resources can learn without a class, and a person who puts no effort in will not learn in even the best class.

But as for I refuse to believe that there is a student anywhere that really wants to learn but cannot. That is true, but only to a degree. There remain plenty of places, even in America, where internet access is limited and a young student in particular may not have the resources to get consistent and frequent internet access. Similarly, there are places where the libraries are not accessible in a practical way.

A truly determined person, such as Srīnivāsa Rāmānujan can rise above, but they are the exceptions and even Ramanujan got help from people to reach his peak.
