Problem: Article: If you're concerned about how the grade(s) will impact your college future, consult with your guidance counselor to create a plan. Perhaps you took courses that were too difficult, or maybe you should explore other majors. With the assistance of your counselor (and perhaps your parents, guardians, or other mentors), create a plan that will get you back on track. Formulate a specific, step-by-step plan that will help you do better next time. Feeling as if you have power over the situation will help you find peace and give you goals to work toward for next time. This plan should include how many hours a week you will study, what grades you want in each of your classes, how you will manage any medical conditions, and how many hours a week you will socialize, work, etc. If you packed last semester's schedule with high-level, difficult courses you may have the answer to why your grades tanked. Even the most highly intelligent individual should give him or herself a break. Try mixing difficult courses with some of your easier or lighter courses for a balanced schedule. The key to staying zen is to now keep up with your studies at a pace that matches what you need to be learning. Staying organized, committed, and persistent will help you to stay zen in your college studies. However, if the studies are not improving after you've made changes, then it's probable that you need to seriously consider changes to the career path you've mapped out for yourself. Spending energy on something that isn't working out for you will only worsen your situation. You do not want to spend sixteen hours a day studying if you are not learning anything. You will only burn yourself out. Find study methods that work for you in the future. There are a few tactics you can do to help improve memory and comprehension: Rewrite your notes every night after class. This will help you recall details. It will also help keep your notes legible. Do ten flash cards a day. Memorize these ten before adding another ten the next day. Memorizing in small batches will help you remember. Take notes as you read. After you're done reading a passage, write down a summary of what you just read. This will help you understand what you read better. When taking notes by hand, use block letters rather than cursive writing. The results are more likely to be legible and it becomes a habit fast. Half of the benefit of note taking is that writing it down tells your brain to put it in long term memory. Test yourself after each passage. Do math exercises that test the principles you just learned. Quiz yourself on historical dates. These recall exercises will prepare you for the real test.
Summary: Make an appointment with your guidance counselor. Develop a plan to improve your performance. Examine your entire schedule. Stay on top of your studies. Study smarter, not harder.

Problem: Article: These are the two types of water filters available for home use. POE systems treat all of the water that enters your home and connects to the water meter or pressurized storage tank. POU systems, however, treat water at the point where it is being consumed, such as a shower head or sink. POU filters can be attached externally or can be installed inline. POU filters that are installed inline filter all the water passing through a pipe. These types of filters are very common and come in many different formats. POU filters include pitcher filters, personal water bottles with built-in filters, and refrigerator filters. They can be mounted to a faucet, under the sink, or the countertop. Smaller carafe-style pitcher filters are good for single people or couples since they only filter a small amount of drinking water at a time. Some people do not like filters attached to their countertop or faucet; see which style of POU filter suits you best. This will help you decide if you need to target any specific contaminants when choosing a filtering system. The Environmental Protection Agency (EPA) requires water companies to provide a consumer confidence report (CCR) every year, which analyzes the water quality in your area. The information is available on your local government website or newspaper. If you want to test the water yourself, call the EPA's Safe Drinking Water Hotline (800-426-4791) for the names of state-certified testing labs, which may offer low-cost or free test kits. You can also go to www.epa.gov/safewater/labs to find out more information. Visible particles in your water can be rust or sediment, and houses that rely on wells often have bacteria in the water. The contaminates your water has will depend on your home. You may discover you do not need a water filter at all because your water contains no contaminants. If you have a family that drinks several gallons of water a day, a single carafe-style filter would need to constantly be refilled, but a smaller family or couple's water needs would be met by a simple filter. If the contaminates in your water are very toxic, you probably want a POE filter to clean all the coming into your house water. On the other hand, if you are only filtering the water for taste, a POU filter on the faucet will suffice. Research the different options. Consider talking to a Certified Water Treatment Professional.
Summary:
Learn about the POE and POU systems. Learn about the different types of POU systems available. Find out what's contaminating your water. Evaluate your specific water filtration needs based on the contaminants in your water and the POE and POU systems.
