If you can replicate what you were doing when you were studying you will help your brain to remember what it was you were studying. For example, if you were chewing a particular flavor of gum while you were studying, you should chew that same flavor during the exam. One of the best things you can do is actually study in the room, in the desk, where you will take the exam. Studying with friends makes the job seem easier and not so tedious. Just make sure that the friend you study with will actually help you, not just play around and waste your time. If you can, take a little time to explain certain things that you are studying to your friend, or have them quiz you on the things you need to learn. You'll be more likely to cement the facts in your head and recall them for the exam. Mnemonics are simply memorization techniques that can help you while you're studying. You can use acronyms to help you, chaining ideas together, or keywords (especially helpful for languages). Acronyms: this is basically a combination of letters, each of which stands for an idea that you will need to remember. For example, the FOIL method in algebra stands for First, Outer, Inner, Last, designating how you're supposed to do an algebraic problem. Chaining creates a story where each word or idea you have to remember cues the next idea that you have to remember. Keywords: for each foreign word you have to remember, pick an English word that sounds like it. Then you'd visualize an image that has both the English word and the foreign word in it. For example: "cabina" is the Spanish word for phone booth. Imagine a cab trying to fit inside a phone booth. You'll be able to recall the image, which will lead you to "cabina." If you visualize a successful outcome, you'll be more likely to actually have a successful outcome, than if you're neutral or negative in what you say about how well you're going to do on the exam. Tell yourself that you will do great. Be confident and don't lose hope.

The unspoken rule of metal concerts is, however, not to wear the shirt for the band you are going to see. Find a band shirt for a similar band in the same genre as the one you are going to see. Black t-shirts or tank tops with graphic designs are always good choices for a rock or metal show. Avoid anything that isn't cotton. If you are moshing or in a large crowd you will definitely sweat! Keep in mind, rockers mix feminine and masculine in their looks, its going to be the accessories that tie this look together. Match your tee with dark green, dark blue, black or dark purple jeans. If you want to style up your look a little more, try swapping jeans for a peplum skirt or fitted red mini. Either of these provides a feminine chic look. Plaid miniskirts are especially popular at punk rock concerts. If you are going to a heavy metal concert and plan to be in the mosh pit, wear jeans rather than a skirt. Military boots, and dark sneakers are all rocker-chic. Again, you want comfort as concerts are typically in packed areas. Nevertheless, this look lends itself to flats rather than heels. Try to wear shoes with a thicker material at the toe. Your feet will be stomped on quite a bit. Experienced metal heads advise to always wear combat boots to a heavy metal concert. Even sneakers won't protect your feet from all the stomping! Keep in mind that rock looks combine masculine and feminine styles. The accessories are really a chance to make your look more feminine. Layer bracelets (cuffs, leather bands, studded bangles, and jeweled wrap-arounds) until you have an eclectic look. Leather studded cuffs and belts are always good accessories for a rock or metal concert. Earrings should be minimal studs. Avoid long necklaces. If you are moshing or dancing at a rock concert, these can get pulled. Simple light make-up and simple hairstyles are best, though. If you are dancing or moshing, your makeup might run. Wear waterproof makeup if possible. Avoid curling your hair too much, as this style isn't really in fashion for a rock or metal look. Ponytails and braids are simple and practical hairstyles for a rock or metal show. Brightly colored hair and mohawk styles are popular for a punk rock look.

Rose oil, lavender oil, honeysuckle oil, and lemon oil are all good choices for potpourri. The essential oil is what will make your potpourri smell good, so be generous with your drops. Display your potpourri in an open container so that the smell can permeate the air. Add decorative stones for some added bling or some cloves for a spicy kick. Replace your potpourri when you can't smell the essential oils anymore. Potpourri generally smells good for about 2 months.
