What to practise.
Keep a reasoned link between structure, conditions and the predicted result. Combine calculation practice in physical chemistry with mechanism-based organic revision and periodic or coordination trends in inorganic chemistry. Record why tempting alternatives fail; a memorised trend without its conditions is less useful than a short explanation you can apply again.

Before you start.
Can I study without starting the timer?
Yes. Choose Study to browse questions and worked solutions. Attempt opens the exam workspace; the timer starts after the quiz content is ready.
Which marking rules apply?
Use the instructions on each paper. Question types and penalties vary by year. Historical linked-answer pairs require the first answer to be correct before the second can earn marks. Common-data questions are scored independently.
Are all GATE years and branches available?
The library is growing. Only the papers listed above are published; a branch guide does not mean its full archive is available.
