Frequently Asked Questions
Does this simulate a chemistry practical?
No. It supports knowledge and calculation decisions; it cannot assess laboratory performance or replace supervised practical learning.
Who takes Chemistry?
Chemistry is one of the subjects named for the academic science stream in the published guide. Current registration routes and eligibility require confirmation with the school or examination administration.
Are the current sitting fee and pass mark verified?
No. These fields are pending primary-source confirmation. Check the current examination instructions and your registered school or centre. The Ministry portal publishes certificate issuance charges; those do not establish the examination sitting fee or a per-subject total.
