Problem: Article: The vagina actually stays quite clean on its own with minimal help from outside cleansers. Like other parts of the body, the vagina has a pH level that needs to be maintained within a certain range - 3.5 and 4.5, to be specific - in order to prevent the growth of unhealthy bacteria and facilitate the growth of good bacteria. Using harsh cleansers can upset the balance, leading to infection, irritation, and even bad smells. Choose an unscented, mild body cleanser, feminine wash or soap to wash the outer areas of your vagina.  People often refer to the entire area "down there" as the vagina, but remember that the vagina is actually the tube-like muscle located inside your body. The vulva, the skin outside the vagina, may be cleansed with no-frills bar soap, as long as you don't find that it irritates your skin. If you do wash your vagina with soap, make sure to thoroughly rinse it with warm water so that no traces of soap are left behind. Soap left inside the vagina can cause irritation. Douching with chemicals that are supposed to make your vagina smell like a field of flowers actually ends up having quite the opposite effect. They wash out all the healthy bacteria that helps your vagina stay clean and infection-free. The chemicals left behind by douches can cause irritation and even burning, and the same goes for feminine sprays. If you keep your vagina healthy using other methods, there will be no need to try to make it smell different.  Scented creams marketed as a way to change the smell of your vagina can cause the same problems, so these should also be avoided. The same goes for scented pads and tampons and scented wipes. If you feel like you absolutely have to use a scent on your vagina, go for something completely natural and chemical free. You can make your own body spray by mixing a few drops of an essential oil like rose, lavender or lemongrass with water in a spray bottle. Use the body spray after showering, and make sure you're completely dry before getting dressed. Keep in mind that there is no evidence that douching prevents infections or helps to protect against STIs. In fact, it is more likely that douching increases your risk. Many women experience an increased rate of vaginal infections when they're menstruating, since having blood in the vagina changes its pH and throws things out of balance. To stay healthy during your period, practice the following habits:  Change your tampon every 4 to 6 hours to avoid toxic shock syndrome (TSS). Tampons absorb menstrual blood, and if you leave them in too long, you're keeping the blood in your vagina where it can change your pH. Make sure you change your tampon every few hours to keep this from happening. Don't use pads or panty liners for longer than necessary. Wearing pads and panty liners all month long or after your period is over can lead to skin irritation. Consider getting a menstrual cup. These rubber cups are inserted in the vagina to catch the blood, then rinsed out with hot water every few hours. Menstrual cups are a chemical-free choice for handling your period, and they can be really helpful if you tend to get irritated by tampons and pads. It's important to wipe from front to back, rather than the reverse, to keep fecal matter from entering your vagina and causing an infection. Use plain, unscented toilet paper to wipe. Avoid using wet wipes or any other product that contains perfumes and chemicals.
Summary: Wash with hot water (comfortably hot but not scalding) and an unscented soap. Don't use douches or feminine sprays. Have good hygiene during your period. Wipe from front to back.

In one sentence, describe what the following article is about: For professors who use pre-made quizzes from their "instructor's edition" textbooks, purchase a copy. Find the correct edition of the book online and buy it. Before a quiz memorise the answers to the questions. This method is good for entry level science, foreign language and/or history classes that pull their quizzes straight from the book. This can be done by talking to an old student or by talking to other students who might have connections in the class. Study straight from the exam, or if you suspect that the exam will be the same, study the answers straight. If you know a professor or teacher will let you come back to finish a test, purposefully don't finish the exam and ask to come back on a later date. Make sure to memorise the topics or questions so that you can look up the answers before finishing the test later. Claim to be sick, go to thee bathroom towards the end of the exam until its over. Or pace yourself slowly. Be sure that your professor will let you come back before using this method as you could actually do worse if he/she doesn't let you finish. As you turn in your exam, if your professor isn't at her/his desk, use a pencil you brought up with you to change or write in answers from the test at the top of the pile. (This is a high risk!) Keep in mind that some classrooms have cameras. Avoid this if the one you are in does have a camera, because if that is the case, it’s much riskier. Knowing the exact format of the exam paper will help for this, so you can write down all important points on a paper which looks exactly like the the exam paper.   If your exam paper is a question/answer type then remember to add one important point as the question and the other as the answer. You also have to include the page number and marks per question (if included). The next thing to do is staple this piece of paper with the original question paper during the test without anyone noticing.
Summary:
Try getting the "Instructor's Edition" version of your Textbook. Try getting an "Advanced/Old Copy" of the test. Try the "Comeback Later" method. Try the "Bring Your Pencil" method. Try the "Fake Exam Paper" method.
