Here’s what I found about the InsightsIAS Secure Synopsis Compilation—a popular resource for Mains answer writing practice:

---

📥 1. Official Secure Synopsis PDFs

InsightsIAS maintains a dedicated “Secure Synopsis” section with monthly compilations that include model answers (synopses) for GS Mains papers 1–4. These span from January 2025, February 2025, through May 2025 and earlier .

• For example, the February 2025 compilation is available on their site and includes complete synopses across GS‑1 to GS‑4 .
• Earlier volumes are accessible under the Secure Synopsis Compilation archive.

🛒 2. Unofficial Mirror PDFs

Some prep blogs (like UPSCPDF.com and UPSCIASMaterial.com) host older Secure Synopsis editions, such as December 2025 and June 2025, covering GS‑1 to GS‑4. These are useful for practice but are dated.
