Remedial classes are useful in helping students who are struggling with basic concepts of a subject. These classes act as a safety valve for struggling students, allowing them to work at the level they are truly on, rather than fail because they are not on the level with the standards of the class. Remedial classes are a positive environment for students suffering from low-self esteem, as they are encouraged to ask as many questions as necessary to understand their subject, rather than feeling pressurized to understand at once.
