Just specify a time period. A school in the sixth grade and junior high school can choose to merge or fill in the educational experience separately, but it needs to clearly indicate the specific time period of primary school and junior high school to facilitate the later personnel to check and verify. Therefore, a school in the sixth grade junior high school can fill in the educational experience and clearly specify the time period. The four necessary items of educational experience are study time, school, major and educational background. These four items are required, so you can fill them in according to the real situation.
