FromBeginning in the spring of 2020, many students suddenly started to take classes by online.

At that time, we were just trying focusing on to getting used to this situation and didn't consider the pros and cons of thait.

So, today's topic is the meaningvalue of online classes.

In my opinion, learning by online has great importance for our experiences and education.

Firstly, we don't need to go school by having itsince we have online classes.

TheA student who live in the USA might be able to take a class of thefrom a profeessor who live in Nigeria.

"The" is used when referring to a specific individual or thing but "a" is used when referring to someone or something in general

This is a wonderful things.

It is singular, not plural

Also, beforeuntil one minute ofbefore starting class, we can do any other tasks, and this situation should be so effective.is very helpful (or useful)

Moreover ,online classes enable students to save thier money.

The use of the word "their" here is unnecessary because it is obvious from context whose money you are talking about.

In many cases, students should pay a lot of money for study circumstances if we haveclasses offered in a real classroom and that iscan be a big burden for them. (or you could say...students pay a lot of money for classes offered face to face...

If schools offer the online classes by, thus cutting the extra cost which is needed for school buildings, there will be more new students who can learn inovative things from all over the world.

And this situation might be generate the next sSteve jJobs in our society.

Generate is okay, but "produce" sounds more natural, at least in American english

When it comes to technical and psychological reasons, online classes have vital merits too.

Typically the word "merits" isn't used with an adjective. It isn't technically wrong, but it sounds a bit unusual

Since, wWe can look at the blackboard closely byusing our laptop and don't have to care ofworry about other students.

Including the word "Since" at the beginning would make this a dependent clause, not a sentence on its own.

Theis private situationcy makes usit possible to consider the contents of the class deepcarefully.

From these thoughts, I recognize that online classes gives us a chance to study byfor low cost and with diversity, and it has profound meaningsly useful.
