Please let me know that "What is the difference between "Out of Syllabus" and "Beyond Syllabus"?"
For example; This question is out of syllabus. Whether the Question is from the course curriculum or it is not from the course curriculum?
In both the cases, the questions are not from the syllabus. For instance, if the test is on the cardiovascular system and you find a question on the muscle attachment of a bone, that would be considered out of syllabus. Why? Because the test was for cardiovascular and not skeletal system.
Anything beyond is exceeding the limits. I've heard out of... more than beyond... in the context of syllabus.
Out of syllabus means from the prescribed syllabus course. (That is, related to the prescribed syllabus course.)
Beyond syllabus means not from the prescribed syllabus course. (That is, not related to the prescribed syllabus course.)
