#### General advice

**hardware.**To make geometrical figures, you need at least two sharpened pencils, an eraser, a dual-decimeter, a square and a compass.

**calculators**is allowed on the day of the event. Take preferably a simple scientific calculator.Remember, however, that before making a calculation on a calculator, you better head to look an order of magnitude of the result.

**thirty-five minutes**at each of the three parts of the test and keep a small fifteen minutes to read it again.

**independent;**you can move to the next year if you block on one of them.

**address issues in order and**carefully, so as to exploit as and when the results found.

**drafting**and

**presentation**of your copy. They account for about forty four points in the note. Insert each question with its reference number. Present the results with a phrase, enclose them eventually.

#### Tips for digital work

**an exact value or an approximate**value. If nothing is specified, you must give an exact value.

**magnitude depending on**

**you must write a literal expression containing the letter**

*x,**x.*To determine this expression, consider the calculation you would if

*x*was a number, and write this calculation by putting

*x*instead of the number. Think simple as possible the literal expression obtained.

**graph, select the axes scale units to obtain a figure of suitable size (neither too small nor too large).**To place a point or to read its coordinates on the chart, do not hesitate to draw parallels to the axes passing through this point.

#### Tips for geometric work

**freehand**face, this helps you to build full-scale figure. Remember to focus on your drawing the statement of the assumptions and the consequences that you can draw.

**perspective**representation, angles and lengths may be distorted compared to reality. Thus, a side face of a cube can be represented in the figure into perspective by a parallelogram, whereas it is in fact a square. However, in reality two parallel lines are always represented by two parallel lines.

**by applying a property or a**theorem. Then make sure that the assumptions necessary for the implementation of the property are checked.
