The purpose of a full-time course is that the students concentrate on their study rather than any other activity, but students doing part-time work along with full-time course is becoming a trend.
Part-time work provides a person with finance that can help him to pay their fees. This reduces the financial load that he has to bear while doing full-time course. Moreover, if the part-time work is in the field similar to that of the course, it can give a person the additional knowledge that will boost his study. It will also be included in his work experience and can boost his job prospects. Thus, part-time work has its set of benefits which cannot be overlooked.
Full-time course is prepared with an assumption that the student is able to devote his maximum time for studies. Hence, it demands more time and effort from the student. A person doing part-time work will be sacrificing his time meant for studies to his work. His schedule will be hectic and strenuous, he will not be able to perform to his maximum potential, and he will not do justice to his course. This will hamper his progress and his results, and can affect even his health.
Hence, it is better if a full-time course is treated as a full-time course. It will stand in the favor of individual if he refrains from part-time work and devotes his time for studies.
