Skipping class is not the point, the point is not to call the roll. If you skip class and the teacher doesn't call the roll, there will be no consequences; But if you skip class and the teacher calls the roll, it may have a little impact on your grades. Every teacher has a different way of doing things. Some teachers like to call the roll Some teachers call the roll only because of the attitude of the person in charge or the requirements of the school, but it will not be linked to the grades. Some teachers will. But generally, as long as you don't miss one-third of the class (roll call), there is basically no problem.

However, it is not recommended to skip class, something is another matter, hehe.

I hope it will be helpful to you and I hope it will be adopted.
