You need to pay attention in class. Don't start chatting with your peers/friends when the teacher turns their back to you. Even better; don't associate with distracting people. You should realize that the people in your class play an important role in how everybody progresses. However, if you are a good student you will do better and achieve your goals. Your friends will be there for you at that time, if they are trustful and of a good reputation. At home, study and do your homework in a place that doesn't make you sleep. It is advisable to have a dedicated study table or desk. Don't do your study work on the bed or in front of the TV, radio, stereo, etc. That would be pointless because you are meant to be thinking about your studies.
If you feel distracted, take a short break of 15 minutes or less, maybe try to read an unrelated story book. But don't start sticking to the book if the time limit is over. Book mark the page and then you can read it later on. You should also have a daily routine/timetable to guide you, but you must follow it through. Don't have regular fights at school; this will move your attention to fighting rather than listening to what your teacher says! Believe me, these are all important guidelines.If you cheat from your friend....always remember cheating will make you lose....because if your friends answer is wrong your answer is wrong too....so don't cheat be honest if you don't know the answer so leave it...if you cheat and you get full marks...the real happiness will not touch your heart....Be honest..Good Luck.. Remember, study well now, and you can have fun after you achieve your goal - guaranteed!
