No, Russia's space exploration is not at an end. While Russia has faced some challenges in its space program, such as budget constraints and technical issues, it continues to be an active player in space exploration. Russia has a long history of achievements in space, including being the first country to launch a satellite and send a human into space. The country is also involved in international collaborations, such as the International Space Station, and has plans for future missions to the moon and Mars. Therefore, Russia's space exploration is far from over. **

Mid-year grades are the grades that students receive at the midpoint of the academic year, typically around the halfway mark of the school year. These grades provide an update on the student's progress and performance up to that point. End-of-year grades, on the other hand, are the final grades that students receive at the conclusion of the academic year, reflecting their overall performance and achievement throughout the entire year. Both mid-year and end-of-year grades are important indicators of a student's academic progress and are often used for various purposes, such as determining promotion to the next grade level or eligibility for certain programs. **

In either case, it's important to reflect on your efforts and set goals for improvement in the future. **

A school year officially ends when all required curriculum and educational activities have been completed, final exams have been taken, and grades have been submitted. Additionally, the school year may end with a graduation ceremony for students who are moving on to the next level of education. The specific end date of the school year can vary depending on the academic calendar of the school or educational institution. **

A year-end report card is a summary of a student's academic performance over the course of a school year. It typically includes grades for each subject, as well as comments from teachers about the student's progress, strengths, and areas for improvement. The report card serves as a way for parents, students, and teachers to track the student's development and provide feedback on their learning. It is an important tool for assessing a student's overall performance and determining their readiness to move on to the next grade level. **
