INPUT ARTICLE: Article: For some schools, especially college courses, each course has a number of credit hours. Credit hours are units schools use to measure the work load. Generally, credit hours are based on mode of instruction, number of hours spent inside the classroom, and number of hours spent studying outside the class. Find out the number of credit hours assigned to each course you are taking. It should be listed on your transcripts or in the school catalogue. Some schools mostly offer 3 credit hour courses, other colleges 4 credit hour courses, and some schools do a mixture. For many schools, labs are 1 hour. If you cannot find the credit hours for each of your courses, talk to an administrator or the registrar. Use the common 4-point GPA scale to assign the values: A = 4 points, B = 3 points, C = 2 points, D = 1 point, and F = 0 points. If your school allots 5 points for upper level classes, such as Advanced Placement (AP) or International Baccalaureate (IB), you will be using a weighted GPA scale. Add .3 for each plus value or subtract .3 for each minus value. If you have an A- in a class, mark it as 3.7. Match up each letter grade with its scale value and write it next to the grade (e.g. B+ = 3.3, B = 3.0, B- = 2.7). To find the GPA, you must do a little bit of math to determine the different values for the scores that go into the overall GPA. Multiply each scale value grade by the number of credit hours to get the grade points. For example, if you made a B in a 4 credit hour class, you would multiply the scale value of 3 for the B by 4 credit hours, which gives you 12 grade points for that class. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/b\/bc\/51457-8b1.jpg\/v4-460px-51457-8b1.jpg","bigUrl":"\/images\/thumb\/b\/bc\/51457-8b1.jpg\/aid51457-v4-728px-51457-8b1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class="mw-parser-output"><p>License: <a rel="nofollow" class="external text" href="https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/">Creative Commons<\/a><br>

<\/p><\/div>"} Add together the number of credit hours you have taken in total to get the total credits. If you took 4 classes that were 3 credit hours each, you will have a total of 12 credit hours. For example, if you have a total of 45.4 grade points in a total of 15.5 credit hours, you would have the following math problem: 45.4 / 15.5 = 2.92. Your credit hour-weighted GPA is 2.92.

SUMMARY: Determine the number of credits. Assign the appropriate scale value for each letter grade. Calculate the weighted scores. Find your total weighted credits. Divide the grade points total by the credit hours total.

INPUT ARTICLE: Article: As with cleansers, there are many different products on the market available for different skin types. You will likely need to find yours through trial and error. In general, if your skin is oily, look for exfoliating products that promise a "deep cleanse." If your skin is dry, find one that is gentle and moisturizing. Work up your face slowly, moving your fingertips in small circular motions. Gentle scrubbing microfiber towels are an alternative to massaging in by hand. Many beauty shops even sell gloves made of this material to make your routine easier. Electric-powered exfoliating tools are also popular. Inexpensive versions of these gadgets can be found at most supermarkets. Use warm water. Avoid rubbing your skin with a towel, as this can irritate and damage your skin. Your skin may be more sensitive after exfoliating. Moisturizing is especially important after exfoliating, as natural hydrating oils are often stripped away in the process. Exfoliating also removes your skin's first layer of protection. While dead, dry skin may make your skin feel rough, it does serve as a barrier over more sensitive skin underneath. Regular exfoliating helps to keep your skin soft and blemish-free. You can reduce frequency if the humidity goes up or your skin is less prone to flaking. If your skin is very sensitive, exfoliating may be too irritating and worsen dryness. Find the right balance that works for you.

SUMMARY:
Find the exfoliating product that is right for your skin. Massage the product onto your skin with your fingers. Rinse the product off and pat your face dry. Moisturize your face. Repeat twice a week before bed.
