This study was conducted with students from the College of Education in Derj to determine their perceptions regarding tests and the criteria for an effective test. The study focused on students' perspectives due to their diverse experiences and ideas about examinations.

A questionnaire was administered to undergraduate students, and SPSS was used to analyze the responses received. The results indicated that most students prefer questions that are simple and easy to comprehend. Students found it easier to take tests when the questions were clear and concise. Students also emphasized the need for fairness and believed that tests should be based on the material that was actually taught in class.

Some students also stated that quizzes and homework were more important than just taking final examinations. Additionally, some participants reported that exam-related stress negatively affected their performance. In general, students preferred tests that helped them learn better rather than tests that focused only on achieving grades.

This research studies the use of code-switching in English classes at secondary schools in Derj. Code-switching means using Arabic with English during the lesson. Many English teachers face problems when students do not understand explanations given only in English. For this reason, some teachers use Arabic to help students understand the lesson better. The study focuses on teachers’ opinions about using code-switching in the classroom. A questionnaire was used to collect data from 32 English teachers. Simple statistical methods were used to check the reliability of the questionnaire and to analyze the results. The findings show that most teachers accept the use of code-switching, but they do not support using it all the time. Teachers mostly use Arabic when explaining difficult vocabulary, grammar rules, or classroom instructions. They also believe that limited use of Arabic makes students feel more comfortable and willing to participate. However, teachers strongly agree that using Arabic too much can reduce students’ chances to practice English. For this reason, they prefer to keep English as the main language in class and use Arabic only when it is really necessary
