Because of the cutting-edge technology, online courses provide students the freedom to study wherever there is internet and let them communicate with professors who are located far away. Online courses are predicted to replace the conventional method of learning, which involves attending classes in a physical classroom, because of its ease. Schools all throughout the globe temporarily switched from using physical classrooms as their primary method of instruction to using online classes exclusively after the COVID epidemic broke out in 2020. The effectiveness of both physical classrooms and online programs might be improved with input from students. Students who have taken both physical classes and online courses at COVID in 2020 are given online surveys as part of this research. The purpose of this research is to compare and contrast the efficacy of traditional campus-based education with that of online learning. Feedback is gathered to evaluate the effectiveness of offline instruction against online learning; variables that affect the efficiency difference are examined and recommendations are made for improving the learning experience.
