Core engineering
Biotechnology Engineering
From biochemistry and genetic engineering to bioreactor design — and the 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.
Biochemistry
Biomolecules, enzymes, metabolism, bioenergetics, signalling
Microbiology
Microbial diversity, growth, sterilisation, genetics, pathogens
Cell Biology
Membranes, organelles, cytoskeleton, cell cycle, apoptosis
Molecular Biology and Genetics
Mendelian genetics, replication, transcription, translation, gene regulation
Bioanalytical Techniques
Spectroscopy, centrifugation, chromatography, electrophoresis, microscopy
Immunology

Genetic Engineering
Restriction enzymes, vectors, cloning, PCR, sequencing, CRISPR
Plant and Animal Biotechnology
Tissue culture, transgenic plants, animal cell culture, transgenics
Bioinformatics
Databases, sequence alignment, BLAST, phylogenetics, structure prediction
Unit Operations and Transport Phenomena
Material balance, fluid flow, heat transfer, mass transfer, thermodynamics
Bioprocess Engineering

Downstream Processing
Cell disruption, separation, chromatography, membranes, formulation
GATE BT preparation
The GATE BT 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 Biotechnology 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.
