The difficulty level and the amount of time required to cover each unit and the respective chapter varies. Therefore, students must try to revise their basics well before going ahead with the new chapters while studying for the exam.
The next step would be to prioritize the chapters according to their weightage of marks. Each unit in the Uttarakhand Board Class 10 Science Syllabus 2021 has been assigned with appropriate marks.
UKBSE Class 10 Science Practical/Sessional Exam
The assignment or the project work performed for the internal assessment is evaluated by an internal subject teacher and an external examiner. Both the internal and the external examiner give marks to the students.
