Hello there, @JasmineGilda ...
There is no specific sir/madam, but there are lots of Community members here to help you. So, hopefully I'll be able to help answer your question.
If you are looking for how to create assignment groups in your course, you can follow this Guide:
Then, you can create assignments within those assignment groups:
So, for example, you might have an assignment group called "Written Assignments" and another assignment group called "Quizzes". Further, you might have a third assignment group called "Graded Discussions". You can create as many assignment groups as you want and then add assignments in those assignment groups. And, if you wanted, you can weight those assignment groups. For example, with the assignment groups in my example, you might have something like:
- Written Assignments - 50%
- Quizzes - 40%
- Graded Discussions - 10%
- TOTAL - 100%
Here is how to weight your assignment groups: How do I weight the final course grade based on assignment groups?
Hopefully this information will be of help to you. Please let Community members know if you have further questions...thanks!
