Indicate: 
 to mention something and give an argumentation or theoretical explanation. 

Demonstrate: 
 to show that which is stated. 

Determine: 
 to define something. For example, to deduce a quantity from a measurement, figure or graph. The answer includes a numerical value and the unit. You can also draw a quantitative or qualitative conclusion based on the data or measurements. Calculations and the use of a table book may be necessary to determine something. 

Calculate or make a calculation: 
 to give a quantitative solution (number plus unit) as an answer to the problem posed. The answer must make sense and the calculation must be realistic. The candidate must show which formulae and data he used. 

Calculate algebrically: or
calculate exactly:
(mathematics A & B) 
 the calculation must be written out on paper including intermediate steps. The use of special functions of a graphic calculator (e.g. solving equations en calculating intersections and slope of graphs) is not allowed. 

Describe: 
 to reflect the observed phenomena. The candidate is required to use the specific technical terminology or conventions. For example, the vector representation or the beam path, if these are relevant. 

Discuss: 
 to describe something in a summarizing way. This includes facts, arguments and opinions. 

Name: 
 to write single words, in a list or otherwise; it is not necessary to give an explanation unless you are explicitly asked to do so. 

Design: 
 to indicate a possible circuit or construction in accordance with certain criteria. 

Give an overview: 
 to divide and name an entire area, using some technical terms. These can be explained and illustrated with examples. 

Draw: 
 to provide an image by means of a drawing. Although you may be required to use conventions (vectors, light beams), it is not necessary to provide geometric constructions that require the use of a ruler and compass. 

Apply: 
 to use a law or formula in the correct situation to come to a solution. 

Explain (1): 
 to give a description and/or drawing with an argumentation, using technical terminology. The explanation can include semiquantitative data. 

Explain (1): 
 to give a coherent story, describing observed phenomena and connecting them to theoretic models. 

Illustrate: 
 to capture certain information in text or drawing in a professional way. 

The set up is schematically shown in a Figure: 
 to clarify the principle a simplified drawing is given. This drawing is usually not on scale.
