Hello

The Silverzone Olympiad answer key is usually released within 3–4 weeks after the exam. For exams held in November or December, the answer key generally comes out in December.
It is published subject-wise and set-wise on the official Silverzone website.
You can check their answers online once the key is released. Final results are declared a few weeks after the answer key.

You can also refer to the link I am attaching below for more details, so that all your doubts will be cleared.
