Core engineering
Petroleum Engineering
From petroleum geology to drilling, reservoirs and production — and the oilfield careers that follow.
Core subjects with Aria
Read the notes, or pick a subject and Aria teaches it from the basics, with the formula first, units checked, and numericals worked step by step.
Petroleum Geology and Exploration

GATE PE preparation
The GATE PE paper covers engineering mathematics, general aptitude and the subjects above. Take timed mocks marked the way GATE marks, or practise any subject with Aria.
PSUs, government jobs and core placements
Many PSUs shortlist engineers through GATE scores; others run their own exams. Recruiting PSUs, cut-offs and eligibility change every year — always check the official notification.

Switch to IT
Plenty of Petroleum graduates get software jobs — service companies hire from every branch. This is the order that works when you haven't coded much.
- 1Aptitude first Every service company tests it before anything else.
- 2One language, properly Java from the basics, with Aria when you are stuck.
- 3DSA, pattern by pattern The problems that actually get asked, in order.
- 4SQL 240 problems on real schemas — a common test round.
- 5Your resume Import it, get an ATS check, fix weak bullets.
- 6Mock interviews Practise the interview before the interview.
