Before your hike begins, you should be well-hydrated. During your acclimation stay, you should be drinking 2 to 3 liters of water each day to prepare your body for the hike. During the hike, keep a 1-liter bottle of water in your pack, and drink often to keep yourself hydrated. If there are stops along the way, refill your bottle, even if you think you won't need it. At higher altitudes, your body will burn energy more quickly, so have some snacks such as dried fruit and nuts, fresh fruit, or a bag of chips to eat as a snack.  You will want the snack to be high in carbohydrates, so you can quickly replenish your lost energy.  Beef jerky, chocolate, and hard candies offer good, light weight snack solutions. This is especially important if your hike begins at a lower altitude and increases steadily. You will notice as you hike that you begin to tire more easily, and you may feel short of breath. Take frequent breaks to recover, and go more slowly. Once you have reached an altitude above 6,000 feet (1,828 m) consider resting for a day or two to give your body some time to acclimate. On a long hike, it can be easy to slip into a state where you aren't really paying much attention to how you're feeling physically. However, when you are hiking at high altitudes, you should remain aware of what is going on with your body, especially as you ascend higher and higher.  If you begin to experience nausea, a lack of hunger, a lack of thirst, or if you notice a headache, are feeling dizzy, having trouble breathing, or losing control of your coordination, stop. Tell another member of your hiking group. Don't ignore these symptoms, as they may be early signs of altitude sickness.  Don't try to tough it out. These symptoms may subside quickly with a bit of rest, but they could also turn into something more deadly if you aren't careful. If and when you start to notice some shortness of breath, stay alert. Focus on taking deep breaths in and out, and make sure that the breaths are even. This will help you avoid over-exerting yourself. If you feel that you are over-exerting yourself, stop and take a break for a few minutes to regain control of your breathing. Each time you ascend another 1,000 feet above the altitude that you live in normally, you should stop and rest for 2 hours. This will give your body a chance to acclimatize, and will help you avoid dangerous consequences of ascending too quickly. This may mean taking more time than you hoped, and may mean camping over night, so be prepared for this reality. If you are on an overnight or multi-day hike, you should not sleep at an elevation that is more than 1,500 feet higher than the elevation at which you slept the night before. For example, if you slept at 6,000 feet the night before, you should not sleep above 7,500 feet the next night. With high altitude hiking, it is important that you be ready to turn around and call it quits if any of your hiking group begin to experience symptoms of altitude sickness. It may feel disappointing, but it is better to be safe than stuck on the top of a mountain with a person who is suffering from severe symptoms of altitude sickness.

Once you have processed the question, look at all the choices presented to you. Most multiple choice exams provide four to six possible answers per question. In some cases, you may only be given two options. Take your time and read over each possible answer. Do not skim or skip over any possible answers. This will ensure you make an informed decision about the correct answer to the question. Put a small mark by answers that appear incorrect right away. You may know that one or two answers are incorrect, or have a strong feeling they are not right.  Eliminate any answers that seem incorrect to you, based on your interpretation of the question.  Look for possible answers that have “always,” “never,” and “none of the above” in them, as they are usually incorrect. When you go over the answers, avoid thinking that your instructor is trying to trip you up with sneaky or confusing options. Most instructors won't give you "trick" answers like this. Ask yourself whether the answer you have chosen fully answers the question. Do not go for an answer that only partly answers the question, as it is likely incorrect. Trust your gut feeling and go for an answer that responds fully to the question and seems correct to you. For example, you may be torn between two answers for the question. Try out both answers for the question. Read the question to yourself and place each answer at the end of the question. Pick the one that appears the most correct to you. Do not skip around on the test and answer the ones you know first. Skipping around can waste valuable time, especially if you are doing a timed exam. Try to work through each question one at a time and in order so you make sure you answer them all to the best of your ability. If you get stuck on one question, try to work through it slowly. If you are really stumped, put a star or mark next to it so you know to come back to it at the very end of the exam. Doing this can make you lose points on the exam. In some cases, leaving the questions blank will gain you no points or the instructor may deduct points. Choosing an answer based on your judgement and knowledge may land you at least one or two points more on the exam. When in doubt on an answer to a difficult question on the exam, go with your best judgement and choose the best answer you can identify from the list of options.

Once you have accepted the person's apology, it can be difficult to actually act on your acceptance and forgiveness. You may still be feeling resentful, hurt, or upset by the person's words or actions and may struggle with how to truly forgive them. One way to process your emotions is to compose a letter to the person that focuses on how and why they hurt you, and how you are going to work towards truly forgiving them.   Be specific and honest. Discuss why you still feel hurt and note that it may take you some time to move past their words or actions. You don't actually have to give the letter to the person; the act of writing down your feelings and addressing the person directly can help you to heal and move on. Another way to put your forgiveness into action is to show the person that you accept their apology. Suggest spending quality time together to show the person you still enjoy their company and want to continue to be friends.  Plan an activity where you both have to work together, like playing a sport. This could show that you're willing to rebuild trust and renew friendship. Suggest doing something that you both enjoyed in the past as a way to show you're willing to move past any negativity and focus on the positive times instead. While you should commit yourself to trying to fully trust the person again, especially if they give you a heartfelt apology and you accept it, you should also be on the look out for warning signs. These could be small moments that indicate the person may make the same mistake again or may be falling back into bad habits that could lead to an issue and the need for another apology. Try to steer the person away from making another mistake or hurting you again like they did before.  For example, if the person is starting to show up late for your dates again, mention it, as they may not be aware of it. Remind them that you find it hurtful when they do this. This may help encourage them to work harder.
