Is it really free? Will money get taken from my account?
Free to try — no signup to start, no card, no auto-debit, nothing taken silently. When you want the full library there are three plans, by length: ₹499 for three months, ₹699 for six, ₹999 for a year. Each is a single payment for that period, not a subscription — when it ends we ask you, and nothing is ever taken automatically. You can also keep learning free by sharing the app, and you can always try before paying anything.
Is this app enough to prepare for the Olympiad?
No — and it isn't meant to be. We train the Logical Reasoning section. The maths, science and Achievers questions are school subjects, best revised from the class textbook and SOF's own sample papers. The same honesty applies to NSTSE: its Critical Thinking section is 5 questions of 60 — the same kind of thinking, but a small part of that paper, and we'd rather say so than sell you something.
Which SOF olympiads have a Logical Reasoning section?
IMO carries the most — 15 questions for Classes 5 to 10, and 10 for Classes 1 to 4. ISO and ICSO carry 10 for Classes 5 to 10. IEO, IGKO, ISSO, ICO and IHO have no Logical Reasoning section at all, so this app won't help with those papers.
There's very little time before the exam. Is this any use?
Some. Practice always beats no practice. But be honest about what an hour for fifty questions means: recognition is built over months, not in a week. Start anyway — this section returns every session, and every reasoning paper after school asks for the same thing.
Is the app in Hindi?
Yes — fully. Choose Hindi and the whole app is Hindi: the questions themselves, the options, and the explanation after each one — not an English app with Hindi labels around it. Worth knowing either way: SOF publishes its own syllabus and sample papers in English.
How much internet does it need?
Almost never. The questions are on your phone, so you can practise on a train, in a village with no signal, on a phone with no data pack. The app checks in with us about once a week to confirm your access is still active — a few seconds, a few kilobytes. That's also when your progress is saved online and when replies to any questions you've asked come through. If you're offline for longer than that, nothing is lost — you just reconnect when you can.
When are the SOF olympiads, and how do we register?
Through the school, and only on SOF's own website, sofworld.org — never through an agent and never through us. SOF publishes an exam schedule each session with the Level 1 dates, and schools register their students. NSTSE is separate and registers through unifiedcouncil.com.
