How we write, check and correct what you read and run on PractiSci.

Who writes it

All labs, theory notes and viva questions are prepared by Surendra Singh Kamboj, founder of PractiSci, following the NCERT Class 11 and 12 Physics and Chemistry syllabus.

How we check it

Every simulation runs real equations and SI units. Each lab is compared with the textbook result before it goes live, and values are tested at the edges, not only at the defaults.

Corrections

If something looks wrong, press Report inside the lab or write to support@practisci.com. We fix confirmed errors quickly and update the date on the page.

Independence

PractiSci is not affiliated with NCERT, NTA or any examination body. See About us for who we are.
