Common questions
Which exams are covered?
All three. Combined Geo-Scientist Mains Chemistry Papers I, II and III are solved for 2016 to 2025; Civil Services Mains Chemistry Papers I and II and Indian Forest Service Chemistry Papers I and II for 2021 to 2025. Geo-Scientist Prelims papers can be read and downloaded, with an online test series. See the coverage table for every paper and year.
Are the solved papers free?
Yes. Every solution here can be read free on this site, page by page: Geo-Scientist Mains 2016 to 2025, and Civil Services and IFoS 2021 to 2025. They are not offered as a download. The book for each paper has all its years in one volume, with every question of every paper answered, the syllabus, topic-wise weightage and an index.
How do I read the book?
The books are Kindle eBooks with fixed pages, so every diagram and table stays where it was drawn. Read them in the free Kindle app on a phone, tablet or computer. Some older e-ink Kindle devices do not open fixed-page books, so check the supported devices on the Amazon page, or send yourself the free sample first.
Can I download the question papers?
Yes. Every question paper listed here can be read on the site and downloaded as a PDF.
Do I need an account?
No. Reading the papers and solutions needs no account. For anything paid, you enter your name and email on the payment page.
How will the test series work?
A full paper is posted on a fixed date. You write it by hand, send a scan of your copy, and get it back with marks and comments on each answer. Dates and fee are not announced yet.
How are paid courses delivered?
After payment you get a join link to a private Telegram channel for that course. Join requests are approved within 24 hours.
I think a solution has a mistake. Where do I report it?
Write to the contact email or post it in the forum with the exam, paper, year and question number. Corrections are announced on Telegram.
