SSC CGL syllabus: what to cover first
Start with Quant (Arithmetic + Advanced) and Reasoning — these decide speed.
Next, revise English vocabulary and reading comprehension from recent CGL papers.
Use PYQCollection year shelves for the last 3–5 years. Mark weak chapters after every timed set.
GS/GK: focus on static + last 6–8 months current affairs; do not chase every random fact.
