While there are Stonehenge only tours, many people choose to combine stops and see more of the countryside, including sites like Bath and Windsor Castle. Expect to spend at least a day of travel on your tour. You can also opt for a two day tour with an overnight stop. Touring companies offer tours of the English countryside, which is where Stonehenge is located. While many of the tours include it as a destination, make sure that your tour includes Stonehenge. You will need to acquire a ticket from the tour company you choose. Depending on the company, ticket purchasing options may vary; however, many touring companies offer online purchase options since international travelers are common. Enjoy your visit to Stonehenge! Remember to keep up with the schedule for your tour group.

Summary: Decide if you want to go to multiple destinations. Choose a one or two day tour. Select a tour company. Purchase a ticket. Take your tour.


If your cat is suffering from bladder stones, time may be of the essence. Stones have been shown to grow to problematic sizes in as little as two weeks. Bladder stone growth may lead to severe pain, vomiting, and depression. If a blocked ureter is not diagnosed and treated quickly, the blocked kidney may become irreversibly damaged. Depending on the severity and location of your cat's bladder stones, your veterinarian may recommend something as simple as a change in diet, or a major surgical procedure.  Your vet may prescribe a special diet that will dissolve mineral deposits in your cat and alter its pH to prevent future deposits.  Your vet may flush your cat's bladder. This involves the use of a catheter to remove deposits and any residual sediment.  Your vet may perform a cystostomy, in which the bladder is surgically opened and the mineral deposits physically removed.  Your vet may recommend a perineal urethrotomy, in which the urethra is surgically widened. If your veterinarian recommends surgery as the best option to remove a severe bladder stone, there are several steps you may need to take to prepare it for surgery.  Have your cat fast before receiving anesthesia. Any time an animal is anesthetized, there is a risk that, if vomiting occurs, it may be inhaled into the lungs. The best way to prevent this is to keep your pet from eating any food prior to the scheduled procedure. Fast times may vary, depending on your cat's age and size, and the specific anesthesia being used on your cat. Consult with your veterinarian to determine how long your cat should fast prior to surgery.  Keep your cat hydrated. Unless your vet advises otherwise, you should be able to give your cat water overnight until the morning of the procedure.  If your cat requires daily medication, ask your veterinarian whether or not to administer those medications prior to surgery. If your cat has undergone surgery, your vet will provide you with the information you need to care for your cat after its surgery. This will probably include giving your cat medication regularly, and may call for more frequent veterinary check-ups. Your vet may want to send the stones away for analysis in a laboratory. Knowing the precise mineral content of the stones can make it easier to determine the appropriate prevention methods, including prescription medication to prevent the formation of future bladder stones.

Summary: Act fast. Consider your options. Prepare your cat for surgery. Provide post-surgical care.


To get into dental school, you will have to take the Dental Admission Test (DAT). This test is given by the American Dental Association. The test has 280 questions and takes five hours to complete. An average score on this test is 19 out of 30. It is taken about a year and a half before you start dental school. Most people take it in the spring or summer of their junior year of undergrad.  The test contains a lot of questions related to natural sciences, along with reading comprehension and quantitative reasoning. A high score on this test is important because dental school is very competitive. For example, some of the top dental schools in the country had hundreds of applicants, but only accepted between 100 and 200. After you complete your degree at an accredited school, you need to meet the requirements to get your license. In most places, this requires that you take exams after receiving your degree. Usually, one exam is a written test that tests your basic knowledge of the field. Your dental school will probably arrange the test for the graduating class to take together. Your state or area will grant your license to practice dentistry. In the US, the exams may vary from state to state. These exams are clinical and require you to perform treatment on patients.  If you plan to practice in your dental school's state, then your dental school will often host the exam annually or semiannually. Some states accept a regional exam, such as the Western Regional Examining Board or the Northeast Regional Board.

Summary: Get a high score on the Dental Admission Test. Pass the National Board Dental Examination written test. Pass your clinical exams.


If you feel the need to cheat or manipulate the test, one thing that most people recommend is to cause yourself mental or physical stress when you are expected to give the answer to a control question. This will give you a higher baseline, so when you tell lies relevant to the case or situation, any spikes in your responses might be smaller than the spike you just created during the control.  Think of a frightening or exciting thought when you recognize an obvious control question. You can also make your heart rate and perspiration increase by trying to solve a somewhat difficult math problem in your head. Try dividing 563 by 42, or some other similar problem. When asked a question relevant to the case or situation, put yourself in a calm state of mind when you answer. By staying as calm as possible, you can prevent many major spikes in your physiological responses.  Essentially, a “lie” only counts if that lie generates a greater physiological response than that which you had while you were telling “white lies” with the control questions. As long as your physiological response to a question and answer produces a less noticeable reaction than any reaction you displayed while answering the control questions, it will probably not count against you. Maintain your breathing pattern and keep in mind that the polygraph is not infallible, and that you are in control of your own physiological response. Daydream about something soothing, like cuddling under a warm blanket with a cup of hot chocolate on a cool night, or taking a relaxing shower or bath. If the examiner catches you trying to cheat the test, you might be asked to schedule another test or the examiner may take countermeasures against further acts of manipulation. Moreover, attempts to manipulate the test might cause the examiner or reviewer to judge your results more harshly once you finish.  For instance, do not stick a thumbtack in your shoe and attempt to press down on it to spike your vitals during control questions. Oftentimes, an examiner will have you remove your shoes during the test to avoid such tricks. In fact, while physical pain will cause your vitals to spike, it is usually easier to catch than psychological stress. Biting your tongue, clenching a muscle, or other similar tactics can be caught easily if you are working with a trained polygraph professional.
Summary: Stress yourself out when answering control questions. Calm down when answering relevant questions. Avoid tricks that are easy to catch.
