Get started on the questions that are worth the most points first, all other things being equal. This will ensure that you are able to answer all the higher point value questions that matter more, rather than wasting time on the questions that count for fewer points. If you finish early, look through all your answers again. Give special attention to questions with underlined words. Don't stop working until the final bell. If you finish early, maybe you missed answering all the questions. Go back and make sure there are other questions (like on the back side of a sheet), up on the blackboard, on sheets you dropped on the floor, etc. You may only be getting half your answers right, but, that could be a passing mark, even a top mark depending on the curve.  Tests can be daunting, but you almost always know more than you think you do. Once you get in there and start taking the test, you will remember a lot more. If you struggle with a section, simply move on and come back to it later. Wasting time on something that you don’t remember at the moment might mean that you run out of time before you can answer questions that you definitely know the answers to. Also, sometimes there will be hints for the question that you are stuck on later on in the test that will jog your memory. Keep moving through the test and come back to the parts that gave you trouble at the end. You could get caught, and get a zero. Or worse. Don't write notes to yourself on your body, where it can be found (instead, use the strategy in #2, above). If you copy wrong answers from a neighbor, teachers are quick to notice this. And forever after teachers will know you as "The Cheat." Spend the effort you might devote to cheating on doing the best possible job you can honestly. If you fail, use the experience to motivate yourself for the next test. This might mean that you will not concentrate and you will not get the grade that you were expecting to get. Also, if the teacher catches you talking, s/he might give you a failing grade and you will not...

TL;DR in Indonesian:
Perhatikan nilai masing-masing soal. Periksalah pekerjaan Anda. Jangan panik dan menyerah. Jangan pernah menyontek. Jangan berbicara dengan teman selama ujian berlangsung.
