You will be given 85 minutes to solve 22 problems in this subtest.
Please read the instructions before you look at the model questions. When you take the TestAS, you will be given the same instructions in the test booklet.
In this group of items, a process or a model has to be transferred to a flow chart or a given flow chart has to be analysed.
The flow charts can contain the following elements:
Beginning of the process  
Decision point: The further process depends on the answer
given to the question set here. Example: If the question "K ≤ L?" is answered with "YES," then the path marked "YES" has to be followed. If the question "K ≤ L?" is answered with "NO," then the path marked "NO" has to be followed. (The answer to the question "K ≤ L?" is "YES" if quantity K is smaller than quantity L, or if both quantities are of equal size. The answer is "NO" if K is larger than L.) 

Operation that is carried out, or an alternative that is selected. In the
example, "n" is set to 1. Examples of notation: M := 2 M is allocated a value of 2. M := M + 1 the value of M is increased by 1. M := M  N the value of M is decreased by the value of N. 

Joining together: Two "paths" are joined together to form a
joint "path."
