Grade 12 - Chemistry - Semester 1

Yes. All courses on cosqool follow the Saudi government school curriculum (the Ministry of Education curriculum taught in public and private schools), covering Grades 1 to 12 for Semester 1 and Semester 2. cosqool also offers Tahsili and Qudrat test-preparation courses.

cosqool operates on a subscription model. Creating an account is free and needs no plan: after you verify your e-mail you can sign in and open the dashboard, your profile and your calendar. Lessons and the other paid features open when your account has active access: a subscription for the school grade or programme you chose (both semesters together) for the duration you picked, or a complimentary period granted to your account. To start, choose your grade or programme and a duration on the Plans page; you can create the account during checkout or sign in to the one you already have, and your selection is kept.

COSQOOL's school courses follow the Saudi Ministry of Education curriculum taught in public and private schools, for Grades 1 to 12 across Semester 1 and Semester 2. Qudrat (General Aptitude Test) and Tahsili (Achievement Test) are separate exam-preparation courses, built around the official test content rather than a school-grade curriculum.

cosqool offers the Tahsili and Qudrat test preps in Arabic, the language of the tests themselves.

No, each subscription covers one grade level. You can add Qudrat or Tahsili to that grade, or subscribe to them on their own. Choosing a 6-Month or Yearly plan instead of Monthly lowers the cost per month for every grade and test-prep package; the Plans page shows the exact current price for each combination.

Every account has one free school-grade change per academic year, whatever the subscription duration. Make the change from Subscription in your dashboard: it applies at once and your access end date does not change. An additional change in the same academic year costs SAR 25, paid in Manage plan before it applies. Unused changes do not carry over, and renewing, changing the duration or leaving and returning does not add another change in the same academic year. The next free-change date will appear in Manage plan once the academic calendar is confirmed.
