How Can I Achieve Straight A's In My O Levels?

Hard work is needed to achieve your goal. Make it a habit  to revise every subject everyday and buy UNSOLVED or SOLVED past papers to do on the weekends. Instead of being a BACKBENCH-ER, try to sit in the front so you make Eye-Contact with the teacher and that is really important so to make sure that you leave a good impression on the teacher. Ask as many possible ( but sensible) question to the teacher and that will lead to a better learning. Subjects like Physics and maths need a lot of practice. Practice makes MATHS perfect, keep this thing in your mind. Clearing your mind of any confusion is the main thing. Whether you are a science student or you are studying business, all the concepts must be clear. Increase your knowledge by reading good books and internet and I bet that it will help you in answering questions in biology and also, improve your vocabulary. Plan a time table for your studies after school. At least 4 hours of hard work are required to reach your goal. You have the rest of your life to do rest of the things. After giving proper time to all the subjects, in your free time, try to read novels and books so to improve your vocabulary and it will also help you with dealing with the English essays, especially the narrative and descriptive essays.
