Marks are not increasing .

I recently started preparing for SSC CGL. To understand my current level, I gave my first full-length prelims mock test without any preparation, just to see where I stood, and I scored 86.5 marks.

Since then, I have attempted around 19 previous-year mock tests, but my score is still fluctuating between 84–95 marks. The surprising part is that now I have done at least some preparation, yet my marks are not improving significantly.

At that time, I had not prepared General Knowledge and General Studies at all, and even now I am mainly attempting the paper based on my Reasoning, Mathematics, and English skills. Despite that, my score seems stuck.

I want to understand why my marks are not increasing and what I should do to improve my score further.
