Expert Author: Wayne Hemrick | Summary If you are a college-bound high school student, you are probably aware that by the time you graduate, you will be in debt for the rest of your natural life (and the corporations who hold your student loans will in all likelihood hound you beyond the grave). Successful completion of one or more CLEP examinations means fewer classes you will have to take at the freshman and/or sophomore level – and at today's inflated tuition rates, that means exceptionally big savings. CLEP prep is an investment in time that will save you thousands of dollars over the course of your college education. Expert Author: Robert Duval | Summary Calculus is a very complicated topic in mathematics. Even the clever people in algebra will need calculus help. Pre Calculus help is needed at the early stages of higher education in mathematics.

Lund | Summary Although few in number, women inventors have played a vital role in bringing creative new inventions to mankind. Women inventors have had to overcome many obstacles that male inventors have not had to face. This makes their story’s all that more remarkable. Expert Author: William J. Lund | Summary A brief peek at some of the inventions I feel are some of the more important inventions of the 20th century. It's hard to decide which ones are the most important, there are so many, these three have all changed our lives dramatically. Expert Author: Marlene Affeld | Summary Have you ever witnessed an avalanche? They are awesome, terrifying and among the greatest dangers to human life that one may encounter in the back country. In the United States, over the past ten years there has been an average of 25 avalanche fatalities per year. The majority of avalanches affecting people are triggered by people. Skiers, snowmobilers and everyone that travels in avalanche-prone areas should remain vigilant and aware. Expert Author: Marlene Affeld | Summary Montana is home to an amazing and fascinating natural phenomenon: Grasshopper Glacier. Near Cooke City, Montana, in the heart of the Beartooth Mountain Range, Grasshopper Glacier is named for the millions of grasshoppers entombed within the lower fringes of its ice. Expert Author: Wayne Hemrick | Summary Proper preparation in the form of focused and consistent CLEP study is what will help you to succeed in taking the CLEP exam. CLEP, or College-Level Examination Program, offers an execellent opportunity for the college-bound high school senior or anyone else wishing to get college credit to do so in a fraction of the time and money required for traditional classes. By taking the CLEP exam, you have the opportunity to earn credits based on material you have already mastered. Expert Author: Wayne Hemrick | Summary CLEP presents an opportunity to earn college credits by taking an examination that measures one's knowledge and mastery of a given subject area. Successful completion of a CLEP test can result in earning up to five credits in a single morning for as little as $25 per credit. Consider that tuition at an average state college or university now costs around $350 per credit - for which you'll have to sit through several hours of lecture and complete hours of reading from extravagantly-priced textbooks as well as pass at least two major exams and write at least one research paper - and the savings become apparent. Expert Author: Wayne Hemrick | Summary Understand that CLEP exams are not unlike the standardized tests students have been subjected to for years, particularly since the passage of NCLB. They differ somewhat in that a CLEP exam actually does attempt to measure the testee's knowledge of a given subject – but it's also a measure of how well someone takes takes. Knowing and understanding this puts you ahead in the CLEP study game. Expert Author: Wayne Hemrick | Summary Remember when going through the sample CLEP test prep exams to time yourself; it's not just about your knowledge, after all – it's about how well (and how fast) you take tests. With all due respect to Aesop, there is little room for the intellectual tortoise in this race. This is why it's also a good idea to review the general test taking skills that enabled you to survive the last seven years of NCLB standardized testing; this means pacing yourself over an extended period of time prior to the day of CLEP testing rather than attempting to ‘cram’ the night before (which is a poor strategy in any event). Expert Author: Henry KH Fong | Summary Chinese calendars have been around since 2600 BC. This makes the Chinese New Year the longest record of time in history. In fact, it is even the largest chronological record. It began when Emperor Huang Ti first introduced the cycle of the zodiac, which is still in place today. Expert Author: Robert Duval | Summary A good math education needs to start very early, as early as in elementary school. However, it is clear that students are not learning math in a way which will help them love it, hence often times, they try to look for help with math.As a consequence, it is not unusual that students simply turn their back to math, and don't end up learning basic mathematical skill which would help them tremendously in the professional lives, in almost every field. Expert Author: Wayne Hemrick | Summary The fact is that even the best self-taught experts in a given field have certain gaps in their knowledge that the right CLEP study materials can help in filling. Even if you think you have completely mastered a subject – for example, you grew up in a bilingual household and know Russian or Spanish as well as you know English – it's a good idea to properly prepare for a CLEP test, because as anyone who has spent any time at all in academia knows, standardized tests virtually never reflect real-world situations. Like the many tests that have been forced on school districts across the country over the past eight years, CLEP is as much a measure of how well you take tests as anything else. Expert Author: Marlene Affeld | Summary Is it possible that certain people can discover water, minerals or oil hundreds of feet beneath the surface of the Earth simply by using their mind? Since biblical times, dowsers have claimed they can find water, buried treasure or hidden objects by using only their senses and a twig. Expert Author: Marlene Affeld | Summary Since biblical times agates have been considered power stones, talismans of protection and healing energy. The agates found in Montana are no exception. Native Americans believed the intriguing stone told stories from the earth mother and provided protection. It was the stone of warriors. Montana Moss Agate is considered by many to be the most powerful of all agates and is said to ward off storms. Expert Author: Marlene Affeld | Summary Montana is a paleontologist’s paradise and famous worldwide for its wealth of dinosaur fossils. Scientists, consumed with a passion to understand the history of life on earth, have discovered over seventy-five different species of dinosaurs in Montana. More dinosaurs have been discovered in Montana than in any other state in the Union. Expert Author: Marlene Affeld | Summary Cave walls and cliff faces bear witness to the travels, hunts and brave deeds of prehistoric hunters and their historic American Indian counterparts that inhabited the caves sporadically for a period of nearly 10,000 years. These early residents of Montana left behind a rich legacy of artifacts and painted images that many feel have magical significance; evocative and mystical, they fire our imagination and connect us with our past. Expert Author: Jennie Gandhi | Summary A passport is like an identity of every citizen. An important credential that is valid for any documentation. However there are a few rules and regulations one has to adhere to get a passport. First let’s understand the passport. The Indian passport is navy blue in colour and has the emblem of India – the four headed tiger emblazoned on the cover. Above the emblem the word, ‘Passport’ is written in English and in Hindi and below the emblem the words ‘Republic of India’ is written in English and in Hindi. Expert Author: Robert Melkonyan | Summary If your home is close to the highway and if you have had a lot of rain in your city recently, then you could expect a lot of thuds and bangs in some days! The problem is - None of those thuds and bangs are pleasant to hear. And if you were surprised to find out what were those bangs all about - Then go to the highway and you would surely find couple of vehicles lying by the ditch.
