The purpose of midterm exams for preparatory level students in English language classes is to assess their progress and understanding of the course material at the halfway point of the semester. These exams are designed to evaluate the students’ language skills, including reading, writing, listening, and speaking abilities. They help the teacher identify areas where students may be struggling and provide an opportunity for students to demonstrate their knowledge and skills acquired during the first half of the course. Midterm exams also serve as a benchmark for students to gauge their own progress and identify areas for improvement before the final exams.
