This book provides candidates with the opportunity to practice topic-wise questions, from earlier years to the most recent. The dedicated efforts of the MS Books team, in collaboration with the leading O/A-Level Computer Science Teacher, have aimed to perfect this resource.
We have included an answer key and mark scheme at the end of each topic, allowing candidates to compare their answers effectively.
MS Books has made every effort to maintain the actual spacing between questions, as per the CAIE format, giving students a realistic experience of attempting the exam.
With confidence in the quality of this resource, we believe it is invaluable in helping students achieve excellence.
Our sincere thanks and gratitude go to Prof. Zeeshan Haider Malik for dedicating his time to compile and oversee this booklet.
