Q: . There is a theory that different people learn better in different ways and that by exposing yourself more to the method that works best for you, you’ll have an easier time studying. Now, there are studies which show that learning styles might not work, but many people feel like this does make a difference in their learning. You should feel free to experiment because as long as it works for you, that’s all that matters. You can find a number of tests online that can help you figure out your learning style. Any one of them is about as reliable as any other and they may give lots of different results. The best route is to pay attention to how you feel and what things feel like they work for you. Have you ever noticed that you learn better by looking at charts or graphs? When you think back to lectures in class, do you remember what the Powerpoint slides looked like better than the actual words your teacher said? These might be indications that you’re strongly drawn towards visual learning. Try to find ways to make the information you study into a visual representation, in order to help yourself remember it better. For example, try using different color highlighters and tabs to color code the important information in your textbook. Have you ever noticed that you have an easier time remembering what your teacher said, rather than what information was written in your textbook? Do you feel like you absorb information better when you listen to music while you study (sometimes even being able to recall the information simply by “replaying” the song in your head)? These might be indications that you’re strongly drawn towards auditory learning. Try to find ways to make the information you study into an auditory representation, in order to help yourself remember it better. Try recording your lectures and playing them back while you drive or before or after you study. Have you ever noticed that you’re happiest when working with your hands? Maybe you tap your foot or fidget with your hands while you’re in class. These might be signs of a kinesthetic learner, or someone who learns best when they’re physically moving. This learning style is more rare than the other two but important to work with if you have it.  Try taking breaks to run around the block or get other brief exercise while you study. This may help you process the information better and keep you from getting too wound up.
A: Evaluate how you learn Work with a visual learning style. Adapt to an auditory learning style. Facilitate a physical learning style.

Article: Typically, super-automatic machines come with their own grinder. If your model does not have a grinder, make sure you invest in one alongside your machine. After all, you will need it to make your espresso! A quality grinder is a necessity when properly preparing espresso for extraction.  Choose a grinder in your budget, as they can get very expensive. When selecting a quality grinder, look for either step-less or stepped grinders. The stepped grinders have separate settings for fine to coarse grinding. Step-less has no pre-set settings, and you can grind the beans as fine as desired. If you don’t want to drink straight espresso, look for a steam wand when selecting your espresso machine. These are metal stems that are usually located towards the side. There is a bit of a learning curve with steam wands, but with some practice you can easily use them to create voluminous milk foam.  To use, first fill up your pitcher with cold milk. Submerge the tip of the wand just below the surface of the milk, and angle your pitcher. Let a small bit of air into your milk, then let the milk heat up to the correct temperature.  These work great when creating lattes and cappuccinos, for example. Steam wands can be slightly difficult to clean, so make sure you wipe down the wand after each use. Many espresso machines come with a built-in frothing option. With a push of a button, these devices heat up automatically and mix your milk instantaneously. This is the most convenient method to make frothy espresso drinks. Many of these models also offer a large, removable milk tank. You can easily pop this in the fridge instead of cleaning it after each use. If you want to make foamy espresso beverages but the espresso machine you are interested in doesn’t have this feature, that’s okay! You can always purchase a separate milk frother. These effortlessly make your foam, but they can have slightly inconsistent results.  To use, fill the internal tank with your milk, and select the froth button. Some machines have settings to simply heat the milk instead of frothing it. Then, in about 30-60 seconds, your milk will be whipped and foamy.  These are not the best for creating luscious, extra frothy beverages. If you are an espresso aficionado and want to invest in a professional system, go with a dual boiler. These have a separate tank for brewing your espresso and steaming your milk, as opposed to single boiler systems which require you to wait for the machine to calibrate between brewing and steaming. The faster you add milk to the espresso, the better and fresher the drink tastes.  Most single boiler systems require the machine to make the espresso shot, turn up the heat to make the steam, then steam the milk. Dual boiler systems complete both of these functions simultaneously. Go with this machine if you want to serve espresso in a coffee shop, for example.
Question: What is a summary of what this article is about?
Get a grinder if your machine does not have a built-in option. Get a machine with a steam wand if you want to create milk foam. Go with a machine with an automatic frother to easily prepare your milk. Use a stand-alone frother if your machine doesn't have a frothing option. Choose a dual boiler system if you want a professional machine.
