Core engineering
Production & Industrial Engineering
From casting and machining to quality, planning and operations research — and the placement paths 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.

GATE PI preparation
The GATE PI 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

Switch to IT
Plenty of Production 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.
