The syllabus for GSA, like all other subjects, was overhauled for CE-2016. As such, we only have last 5 years of relevant material.

The only trend as of this year is that Science part (minus the maths portion) ALWAYS contain questions regarding the Scientific or natural phenomenon of the preceding year. For example, in 2015 October earthquake hit Pakistan. So in CE-2016 questions regarding Earthquake (example Richter scale, depth, intensity, locus shockwave etc) were asked. Building on this, you can assume that for CE 2021, questions regarding virus, eclipse etc will definitely be asked.

Likewise, once you put the past papers (2016-2020) and the syllabus side by side, and mark the areas of the syllabus of each year, you'll start to see a pattern in the questions presented in the GK-1(GSA) paper. Also, as a general rule of thumb question/areas questioned in the last years paper are 98% of the time not asked for the next year's paper. Building on both these strategies, you can almost cut down the syllabus in half.
