When asked if examinations are good or bad, the answers of different individuals will certainly differ. Some people have the opinion that examinations are good while the others disagree. From my point of view, examinations are good. I have my own reasons for saying so.
The first reason is that examinations help student to identify their strengths and weaknesses in certain subjects. After an exam, students will have a better idea which subjects they are weak at. They can receive private tuition or put in more efforts to improve their performance in the weaker subjects. From examination results, teachers are able to identify the weaker students and assist them to do better. Examinations also help to show a student's learning ability. For example, PT3 examination results help a school to decide which stream students should be in for their upper secondary education. Without PT3, the streaming of students would be much more difficult.
The second reason is, examinations help students to manage their time properly. Most students will study hard in order to pass their exams with flying colours. Since examinations motivate students, they will spend more time on their studies and plan a timetable. When students spend more time on their studies, they can avoid involving themselves in unhealthy activities such as smoking, getting into bad company, wandering in town, spending too much time on the Internet, playing too much computer games, drinking alcohol, et cetera.
With examinations, students will make wise use of their allowance. They tend to spend their pocket money on reference books so that they can increase their knowledge. For instance, when a student purchases books like the model essay books, they can improve their essay-writing skills. Apart from that, students can also buy past year exam paper workbooks or model exam paper workbooks for practising purposes, since 'practice makes perfect'. This can also help them to get used to the exam format and they will likely sit for the exam with confidence.
Examinations are good because they are the driving force for students to study hard. In return, they acquire knowledge which comes in handy when they grow up and start working in the society. Without examinations, most students will not really make an effort to study hard as there is no motivation for them to achieve success.
In a nutshell, although there are disadvantages for students to have examinations, the benefits far outweigh the disadvantages. Therefore, I strongly believe that examinations are good.
