Call up your local city or county government and ask if you're allowed to do home electrical work by yourself. In some cases, you may need a special permit, or the work may have to be done by a licensed contractor. Even if you feel like you can handle the work yourself, you should still see if a permit is necessary. Doing the work without a permit, if one is required, might violate your homeowner's policy. Many bathroom fans are hard-wired through your ceiling or attic. Some, however, have a standard electrical plug that feeds into a regular outlet. You'll want to replace your fan with one of the same type. If you aren't sure which kind you have, pop off the fan's cover and inspect how it is powered. Take a trip down to your local home supply store, and you should be able to find several models of bathroom fans. Look for one with a low “sone” number (2 or less), and a high “CFM” (Cubic Feet per Minute) number.  Sones measure the loudness of a fan. The lower the number, the quieter the fan. CFMs measure the number of cubic feet of air a fan can move out of a room per minute. Generally, the higher the number, the better. High CFM fans may not be necessary for small bathrooms. If your bathroom is large, however, you'll really want to get a fan with a high CFM rating. You shouldn't need anything that's too unusual, and you may already have some tools and supplies at home. If not, pick these up while you're at the home supply or hardware store:  Drop cloth Screwdriver Circuit tester (AKA voltage detector -- the non-contact variety will be easiest to use) Drill and bits Drywall knife HVAC tape Wire connectors Removing your old bathroom fan and working with your ceiling can cause an avalanche of dirt and debris to rain down. Make clean-up easier by laying a drop cloth down on the floor of your bathroom underneath the fan. You may also want to cover the counter or other areas if they are near the fan. Head to your circuit breaker and flip the switch marked for the bathroom fan (or all of the bathroom switches, if there's not one specifically marked for the fan). You definitely don't want to be working on the fan wiring while the electricity is still running!

One-sentence summary -- Check if a permit is necessary. Double-check the type of fan you currently have. Select your new fan. Gather your tools and supplies. Lay down a drop cloth. Turn off power to the fan.

Q: Grade ranges vary among professors and teachers. If your professor or teacher provided a syllabus at the beginning of the year, it may list the grade range. Your school handbook may have this information as well. If you cannot find a range on any of your materials, ask your professor or teacher. Although there are variations, this is the most common grading range for schools and universities in the USA. A "B" or higher is typically considered a "good" grade. A D is the lowest passing grade, but it may not fulfill requirements for further courses or college applications.   An "A" is 90% to 100%. A grade of 100% is an "A+".A grade of 94%-99% would be considered an “A.” A grade of 90%-93% would be considered an “A-.”  A "B" is 80% to 89%.  A grade of 87% or higher would be considered a “B+.” A grade of 83%-86% would be considered a “B.” A grade of 80%-82% would be considered a “B-.”  A "C" is 70% to 79%.  A grade of 77% or higher would be considered a “C+.” A grade of 73%-76% would be considered a “C.” A grade of 70%-72% would be considered a “C-.”  A "D" is 60% to 69%. A grade of 67% or higher would be considered a “D+.” A grade of 63%-66% would be considered a “D.” A grade of 60%-62% would be considered a “D-.”  An "F" is 59% and below. An “F” is a failing grade, so professors and teachers do not usually assign + or – values to “F” grades. The United Kingdom uses several grading scales in primary and secondary school, for tests such as the GCSE and A-levels. These have their own classification terms, but the percentages roughly correspond to the following. This system is also used for undergraduate work in the UK and in India.  70% to 100% is the highest grade, a mark of Distinction. 60% to 69% earns a Merit. 50% to 59% is Pass. Some schools Fail at 49% or below, while others fail at 39% or below. At a university level, the Canadian grading system is similar to the US system, but there are some differences in percentage range:  An "A" is 80% to 100% A "B" is 70% to 79% A "C" is 60% to 69% A "D" is 50% to 59% An "F" is 49% and below
A: Check your course materials for a grade range. Know the typical grading range in the United States. Learn the normal English marking system. Familiarize yourself with the Canadian grading system.

Article: Are you writing to introduce yourself to a particular audience, or is your bio to provide a general introduction to whomever? A bio written for your Facebook page will be very different than a bio written for a website. Some social media sites, such as Twitter, restrict your bio to a certain number of words or characters. Make sure you use that space to make the biggest impact possible. This information will vary depending on who you're targeting as your audience. For a strictly personal bio, you can include details such as hobbies, personal beliefs, and mottos. For a bio that falls somewhere between "professional" and "completely personal," consider sharing details that give a sense of who you are but are not likely to alienate others. Like a professional bio, your personal bio should give your reader a clear idea of who you are, what you do, and how well you do it. However, you can be more informal in your tone than you would in a professional bio. Joann Smith is a passionate knitter who also happens to own and run her own paper supply company. She has been in business for over 25 years and has won multiple awards for business innovation (although never any for knitting). In her copious free time, she enjoys wine tastings, whiskey tastings, beer tastings, and wine tastings. These words are so overused that they have ceased to mean anything to most people, and they're too general to convey real meaning: "innovative," "expert," "creative," etc. Show through concrete examples, don't just tell. A personal bio is a great place to connect with your audience through the use of humor. This can help break the ice between you and your reader, and convey a sense of who you are in a few short words. Hillary Clinton's Twitter bio is an excellent example of a very short bio that conveys a lot of information in a humorous tone: "Wife, mom, lawyer, women & kids advocate, FLOAR, FLOTUS, US Senator, SecState, author, dog owner, hair icon, pantsuit aficionado, glass ceiling cracker, TBD..."
