Wassce Integrated Science Past Question Quizzes

Preparing for the WASSCE Integrated Science paper? One of the most effective ways to build confidence and pinpoint your areas for improvement is by working through past-question quizzes under exam-like conditions. These quizzes help you:

Familiarize yourself with the style and level of difficulty of real exam questions.
Identify knowledge gaps early, so you can focus your revision efficiently.
Build exam stamina and time-management skills, ensuring you can complete all questions within the allotted time.

Before you begin, grab a timer, some blank paper, and a pen. Set yourself 30 minutes, the typical time allocation for a 40‑question objective section and work through the questions without any interruptions. Ready? Let’s get started.
