Then move to CSAT-focused concept articles – Resources 6–8 – to understand exactly how UPSC frames such questions and what “most appropriate” means in an administrative context.

Practice and speed-building (continuous):

Use Resources 9–11 for written practice (10–20 questions at a time) with full reasoning review.

Stage 2 (2–3 days): Build conceptual orientation – Resources 4–6 – to understand what GMA means in CSAT terms and how it overlaps with reasoning and numeracy.
Stage 3 (5–7 days): Do foundation mental-ability practice – Resources 7–9 – solving 20–30 questions per day for speed and comfort.
Stage 4 (7–10 days, and ongoing): Focus on CSAT-linked GMA topics from Resources 10–12 and solve exam-like questions from Resources 13–14 as mixed sets to simulate CSAT conditions.

Basic graph/table concept (Class VIII–X level):

Work through NCERT Data Handling with any one primary solution source (Resources 1–4) and support from 5–6 if needed; focus on reading graphs, understanding scales, and correctly computing basic measures like percentages and averages.

CSAT‑specific DI and data sufficiency concepts:

Read IAS Score’s article (Resource 7) to understand how DI functions within CSAT and what examiners expect.
Then study the Toppersnotes PDF (Resources 8–10) to systematically learn all DI forms plus Data Sufficiency approach for CSAT.

Exam‑oriented practice and speed-building:

Use Gokulam SeekiAS DI set (Resource 11) as a regular short quiz (e.g., 5 questions in 7–8 minutes) to simulate exam pressure.
Solve the Sunya IAS DI PYQ PDF (Resource 12) in larger chunks (e.g., full sets of 10–15 questions) to train pattern recognition and elimination techniques based on units, proportions, and rough calculations.
