Hello Ricardo, "Get" is a verb to receive. For example, "let me get you a drink"... Or, "Would you like me to get you anything from the market?"... etc. etc. And used in the past tense, it would be "Got". For instance, "I got myself some lunch earlier..." "Take" is also a verb (though it can also be a noun), but it refers to the action of obtaining control of something, or removing something. For example, "May I take your bags, Sir?", or "Take him away!" (that means, remove him from this place). The past tense would be "took". Note also that take can be used in another way; for example, "how long did it take you to learn English?" I hope the above helps, but do let ke know if you require further assistance.

To get =to wait until something is given then to get it. To take =to take something yourself w/o being given it.
