What MJPRU asks
The topics already asked
Three papers (2025-26 end-sem, 2025 Mid-1 and Mid-2), every question tagged. The bar shows how many of the three asked it.
The pattern. Four of the eight mid-sem questions came back in the end-sem almost word for word (CIA model, one-way hashing, DSA, cyber law and copyright), and two more came back as close variants (Playfair → substitution vs transposition, e-mail policy → need for security policies). Learn every mid question first. See the full analysis →
