The terms "elective" and "core" are the most significant distinctions. Core courses are obligatory; elective courses are optional; students choose whether or not to take them. Students who choose to take an elective are usually more interested in the content and eager to study because they would not have chosen it otherwise.Other changes that could appear include:1. Core course curricula are more likely to be dictated by someone "higher up" than the teacher—a committee, a dean, or the state board of education. (Standardized testing may be used as well.) In elective classes, professors often have more latitude to teach whatever they wish.2. Electives feature a lower student-to-teacher ratio.3. Electives are typically taught by a single instructor, whereas core courses are taught by a group of instructors.4. Core courses are normally provided once a year, whereas electives are only offered once a year or even less frequently.Furthermore, you can avail all the well-researched and good quality chapters, sample papers, syllabus on various topics from the website of Vedantu and its mobile application available on the play store.
