TS EAMCET 2025 BiPC Exam Difficulty Level (Expected)

According to TG EAPCET 2025 past year trends:

Botany and Zoology (Biology) is expected to be of moderate difficulty level with mostly NCERT based questions. Plant Physiology, Human Anatomy, Genetics and Animal Diversity will be some of the most asked topics.

Physics is expected to be tough and lengthy due to the numerical problems. The most asked questions are expected from Thermodynamics and Mechanics and they might be slightly tough.

Chemistry is expected to be the easiest section and the most scoring. The questions are expected to be mostly direct with some tricky questions from Organic Chemistry. Most asked topics include Chemical Bonding, Hydrocarbons and Thermodynamics.
