It is always possible to get extra lessons for learning English or math. These are are not subjects that most American students like that much. But English tutors or maths tutors can greatly improve the performance of a student in these subjects. Tutoring goes back to before the days of modern schooling. In the Medieval or Renaissance period, tutors were often attached to aristocratic houses to educate the children.
Since that time receiving extra lessons has become, in relative terms, less expensive. It is very possible for people to receive the extra lessons that they need without spending an arm and a leg on it. Sometimes a school will provide these extra lessons for free, though this is not always the case. However, there are a lot of venues where people can receive improved education options.
For example, it is now more possible than ever to receive extra lessons through online learning. There are a lot of online information programs like the Khan Academy, which famously made mathematics available to everyone. But this is not the only way that people can receive training for online learning.
Online learning should not be considered a substitute for face to face education. There are a lot of ways that face to face education has advantages over online tutoring. For example, it is possible for people to find a tutor who can address specific questions the student may have. This is not an option that people have with online learning.
Nonetheless, online learning is a good idea to the extent that it is one of the most efficient modes of delivery. It can be reused again and again. And it is for this reason that online learning will probably remain popular in the future. There are a lot of good teachers out there, and now they can reach almost any student in the entire country.
