PDE MARATHON PDF- 2025 JAN PYQ BY SHEEMAL BHAGI - UGC NET June 2025 Paper 1 & Paper 2 Schedule

Sep 20, 2026

UGC NET June 2025 PDE marathon material by Sheemal Bhagi covering Paper 1 (People & Environment, Logical Reasoning, Research Aptitude, Communication, Teaching Aptitude) and Paper 2 commerce units. It provides a tentative schedule with dates and times for each unit and includes selected question practice. The content explains key concepts like threshold dose/NOAEL with why other options are incorrect, and hard groundwater treatment sequence steps such as aeration, pre-chlorination, coagulation, softening, sedimentation, filtration, disinfection, pH adjustment, and storage.

FAQs

What does threshold dose mean in the given UGC NET question?

Threshold dose refers to the maximum dose at which no adverse effect is observed (NOAEL). It indicates the safe exposure limit before toxicity starts.

Why is the option “highest dose at which no toxic effect occurs” considered correct?

Because it aligns with the NOAEL concept: there should be no adverse effect at that dose level. The other options are ruled out as they contradict the intended definition or framing.

What is the correct step sequence for treating hard groundwater as described?

The notes list the typical order: Aeration (oxidation), pre-chlorination (optional), coagulation and flocculation (if required), softening (when hardness is high), sedimentation, filtration, disinfection, pH adjustment (if needed), and finally storage and distribution.
