Here is an assessment with 100 questions for class 6 subject science. Assessment and tests are very helpful to see where we are and what we need to do more. Assessments and tests lead the teachers to plan the lesson. A teacher can examine his teaching process if it is effective or not. So, it is very necessary to take the tests and exams. At this forum, we provide assessments and tests for teachers as well as students so that they come to know the effectiveness of their teaching and learning process. These assessments can be downloaded as image forms that are printable in A4 size.
