4-month preparation plan
- Month 1: finish NCERT Science (Class 6–10) and Arithmetic (percentage, ratio, time & work, SI/CI). Start daily current affairs.
- Month 2: complete remaining Maths (geometry, mensuration) and all Reasoning topics. Continue static GK (Lucent or equivalent).
- Month 3: start full-length mocks — one every two days. Analyse every wrong answer. Revise science and GA notes weekly.
- Month 4: one mock daily. Last 15 days: revise formula sheets, error log, 6-month current affairs compilation. Start PET practice (running + weight).
