Hello, #Vivers! Mathematics is one of the most important subjects in any educational system. So much so that most of the entrance exams to higher education have this subject as their core subject, which appears in ESO and Baccalaureate. Today, our Mathematics teacher, Charo, explains to us the 7 keys to adequately prepare Mathematics exams in a video that can be useful for secondary school, high school, EvAU EBAU or PCE UNED selectivity students, or access to vocational training cycles. .

For many people, the word mathematics causes dizziness and nausea, but we know an infallible remedy against this discomfort. With a spoonful of 'The Good Professor' syrup and the following tips you will make the symptoms disappear.

### The 7 keys to passing the Selectivity Mathematics exams EVAU EBAU or PCE UNEDasiss, access tests to FP, secondary or baccalaureate

#### **1. Practice every day for 30 minutes**

To get a 10 body you have to exercise throughout the year. In the same way, to have your brain in shape you have to study regularly. An essential requirement to master the subject of Mathematics is practice. Training daily is essential to achieve operating fluency and to consolidate the acquired content. Doing a couple of exercises every day related to the content seen in class or writing down your notes are very useful strategies to ensure passing. I recommend that you start by doing problems that you have already solved. Face a problem only when you know how to do all the exercises solved. For this advice to be effective, before starting to practice, try to have a good understanding of the content that has been explained in class. Ask your teacher any questions. It is possible that while you are reviewing new questions arise, if so, write them down and tell the teacher in the next class.

**2. Read the statement carefully and, if you can, draw a drawing**

If you want to face a problem and not die trying, try:

- Read the exercise carefully, as many times as necessary, to find out what they are asking of you. Many times we know how to solve the problem, but since they speak to us in 'Aramaic' and we don't understand it, we don't solve it. Conclusion: translate the statement into your language.
- Once we have understood the problem we proceed to collect the information it contains. A good trick is to analyze each sentence separately, since each phrase will provide a series of different data.
- Even if you are not Picasso, it is recommended that you make a diagram or a drawing that reflects the problem (in analysis and geometry it is an almost mandatory requirement). Generally, representing the data, in addition to helping us understand the exercise in greater depth, allows us to find the solution or solutions for it. In fact, in many cases graphical representation is supported as an answer.
- Finally, take out your arsenal of formulas and get to work. We only have to connect the information obtained to respond to what they ask of us.

This point is especially important when facing Mathematics exams, whether they are Selectivity EvAU EBAU or PCE UNED, an access test to training cycles or a secondary or baccalaureate exam, since in the exams it is the most We get nervous and make more mistakes by not reading carefully what they ask of us.

**3. Check the calculations**

A maxim of the Mathematics exams, whether EBAU or PCE, is to review the calculations. Between the nerves and the tiny keys of the calculator, the difficult thing is not to make mistakes. It is advisable to do a review at the end of each exercise and not at the end of the exam. If the review is not done progressively, it is easier to get lost and not realize the mistakes we have made. Personally, I think it is preferable to do two problems well than to do five wrong. Another important detail is to try to be clean and orderly. The teachers value it very much.

**4. Be careful with the calculator mode (DEG or RAD)**

Imagine how horrible it would be to have taken a flawless exam and have all your calculations wrong due to poor programming on your calculator. To prevent this from happening, make sure your most precious tool is in the correct mode. Remember that your calculator must have the 'DEG' mode activated if the angles you are going to perform in the operations are in degrees, and have the 'RAD' mode activated if the angles are in radians.

**5. Matrices and determinants**

As you already know, there are certain strategies that must be handled with ease, since we will surely need to apply them at some point during the exam. In relation to the block of matrices and determinants, calculating inverse matrices and solving determinants are two things that you have to know how to do with your eyes closed. There are several ways to find the inverse matrix of a matrix, but it is usually calculated using a formula that involves the adjoint matrix of the transposed matrix and the determinant. I suppose that after reading this paragraph you have gotten chills, so that this does not happen again, review these concepts. Another essential tool is the famous 'Sarrus Rule' which is used to calculate determinants of dimension 3×3 (order 3). You have to know how to solve determinants of any dimension, but order 3 determinants are the ones that appear the most in the exercises.

**6. Geometry**

Geometry is one of the oldest sciences. The Babylonians and Egyptians were the first to use this branch of Mathematics to solve problems in everyday life.

Knowing and using certain geometric strategies can be very useful, not only to pass our exam, but also to solve real-life problems. Handling the scalar product, the vector product and the mixed product is important, since it will help you, among other things, to be able to calculate areas and volumes. Likewise, knowing how to construct the different geometric elements (points, lines and planes) and calculating their relative positions and distances is also relevant. I advise you to make a summary of all the formulas so you can consult them at any time.

**7 Analysis**

Like geometry, the analysis of functions is one of the most appreciated parts of Mathematics since we can visualize the possible solutions to the exercises through their graphic representation. Possibly what is most difficult is deriving and integrating, but with a good teacher and a good table we will not have any problems. You just have to follow the rules and practice. You also have to know how to calculate limits, among other things to be able to represent functions (calculation of asymptotes, study of continuity and differentiability...). This implies knowing the types of indeterminacies that exist and the different strategies that exist to resolve them. If you manage to manage yourself in these two areas, you have most of the work done.

I hope that this is the beginning of a great friendship with Mathematics and that these tips will help you pass your EvAU EBAU or PCE UNEDasiss Selectivity Mathematics exams, FP or secondary or baccalaureate access tests.

For my part, it has been a pleasure to be able to offer you my help. Remember that studying Mathematics is like studying a language, at first we don't learn anything, but as we progress we end up understanding. And believe me, it is very useful to know math.
