Digital TestAS has been applied since 2022. Since the question types are new and there are not many candidates who have experienced it, I cannot comment on its difficulty. In addition to all these, the lack of any resources for exam preparation stands out as a disadvantage.
The fact that the question types in the Digital Testas Core Test can be produced computer-aided encouraged me in this regard. I have designed computer-generated worksheets for you to prepare for the Latin Square and Figure Sequences sections. The questions are randomly generated by the computer. You can repeat them indefinitely and as many times as you want. Have a good practice.
