Analysis of GSA Trends:
The trend in GSA strongly favors scientific constants, definitions, and essential measurements found in fundamental physics and chemistry.
1. Fundamental Physics and Measurement:
The most heavily recycled question across the entire compilation is the definition of Light Year as a unit of distance, appearing across almost every year tested in the compilation. Similarly, the explanation for the blue color of the sky (Rayleigh Scattering) is a recurrent favorite.
2. Applied Technology and Chemistry:
Applied science, such as the principle behind Sonar and the non-changing composition of alloys like Bronze or causes of water hardness, forms a reliable pool of repeats.
3. Basic Computing/Digital Literacy:
Questions covering core concepts in IT, such as the size of a hexadecimal number in bits and the designation of Beta software, indicate a baseline knowledge of computer science terminology is expected.
