Bananas contain three natural sugars - sucrose, fructose and glucose combined with fiber. A banana gives an instant, sustained and substantial boost of energy. Brain Power: Research has shown that the potassium-packed fruit can assist learning by making students more alert. Stress: Potassium is a vital mineral, which helps normalize the heartbeat, sends oxygen to the brain and regulates your body's water balance. When we are stressed, our metabolic rate rises, thereby reducing our potassium levels. These can be rebalanced with the help of a high- potassium banana snack.

Hints for SUCCESS
When you put your best effort in your work, then you have succeeded. So always give your best! When in doubt, ask. Otherwise, you will end up having to spend even more time studying to catch up. Figure out your most productive times of the day and work the hardest parts at those times.
Review EVERYDAY
Do your best to answer any set of questions as if they are the exam. Score them and keep track.
Remember to concentrate on understanding.
Make your books a study tool.
Be involved and ready to learn, not to be taught Remember, the person that gets to the top didn't fall up there!
1. Read the question before you look at the answer. 2. Come up with the answer in your head before looking at the possible answers, this way the choices given on the test won't throw you off or trick you. 3. Eliminate answers you know aren't right. 4. Read all the choices before choosing your answer. 5. If there is no guessing penalty, always take an educated guess. 6. Don't keep on changing your answer, usually your first choice is the right one, unless you misread the question. 7. A positive choice is more likely to be true than a negative one. 8. Usually the correct answer is the choice with the most information. Tips on answering multiple choice questions:

Why does AWS Require an Open book Exam? Back to the AWS B5.1 to see what our job is
Which of the above WI duties requires the use of some reference document?
Okay, Let’s break it down a little more...
It is essential for the Welding Inspector to study all applicable documents before the start of a job
WHAT IS A "CODE" AND WHAT CAN WE FIND IN IT?
• Created by committee of technical experts and represent all interested parties such as manufacturers, end users, inspection authorities and government agencies
• Arranged systematically for easy reference
• Govern design and fabrication of welded components
• Documents that have significant influence upon public health and safety, sometimes adopted by legislative bodies or by federal regulating agencies (legal status)
