The Zimsec O'Level Combined Science Green Book is a document that was produced by the Zimbabwe School Examinations Council (ZIMSEC) to help students revise and prepare for their O'Level Combined Science exam. The exam covers three subjects: Biology, Chemistry, and Physics. The green book contains past exam papers for these subjects from 2018 to 2019, along with their marking schemes. The marking schemes show how the examiners awarded marks for each question, and provide explanations and comments where necessary. The purpose and benefits of the green book The main purpose of the green book is to provide students with an opportunity to practice their knowledge and skills in Combined Science using real exam questions. By doing so, students can: Review the topics and concepts that are covered in the syllabusTest their understanding and application of these topics and conceptsIdentify their strengths and weaknesses in each subjectImprove their time management and exam techniquesGain confidence and familiarity with the exam format and expectations The benefits of using the green book are numerous. Studies have shown that practicing with past exam papers can improve students' performance and grades significantly. It can also reduce anxiety and stress before and during the exam. Furthermore, using the green book can help students develop a positive attitude towards learning and studying Combined Science. The content and structure of the green book The green book consists of four sections: Biology, Chemistry, Physics, and Practical. Each section contains two papers: Paper 1 (Multiple Choice) and Paper 2 (Theory). Each paper has 40 questions, except for Practical, which has 20 questions.

A country of roughly 15 million people as per 2022 census,[15] Zimbabwe's largest ethnic group are the Shona, who make up 80% of the population, followed by the Northern Ndebele and other smaller minorities. Zimbabwe has 16 official languages,[3] with English, Shona, and Ndebele the most common. Zimbabwe is a member of the United Nations, the Southern African Development Community, the African Union, and the Common Market for Eastern and Southern Africa.
Beginning in the 9th century, during its late Iron Age, the Bantu people (who would become the ethnic Shona) built the city-state of Great Zimbabwe; the city-state became one of the major African trade centres by the 11th century but was abandoned by the mid 15th century.[16] From there, the Kingdom of Zimbabwe was established, followed by the Rozvi and Mutapa empires. The British South Africa Company of Cecil Rhodes demarcated the Rhodesia region in 1890 when they conquered Mashonaland and later in 1893 Matabeleland after the First Matabele War. Company rule ended in 1923 with the establishment of Southern Rhodesia as a self-governing British colony. In 1965, the white minority government unilaterally declared independence as Rhodesia. The state endured international isolation and a 15-year guerrilla war with black nationalist forces; this culminated in a peace agreement that established de jure sovereignty as Zimbabwe in April 1980.
The name "Zimbabwe" stems from a Shona term for Great Zimbabwe, a medieval city (Masvingo) in the country's south-east. Two different theories address the origin of the word. Many sources hold that "Zimbabwe" derives from dzimba-dza-mabwe, translated from the Karanga dialect of Shona as "houses of stones" (dzimba = plural of imba, "house"; mabwe = plural of ibwe, "stone").[18][19][20] The Karanga-speaking Shona people live around Great Zimbabwe in the modern-day Masvingo province. Archaeologist Peter Garlake claims that "Zimbabwe" represents a contracted form of dzimba-hwe, which means "venerated houses" in the Zezuru dialect of Shona and usually references chiefs' houses or graves.[21]
Archaeological records date archaic human settlement of present-day Zimbabwe to at least 500,000 years ago.[27] Zimbabwe's earliest known inhabitants were most likely the San people, who left behind a legacy of arrowheads and cave paintings. Approximately 2,000 years ago, the first Bantu-speaking farmers arrived during the Bantu expansion.[28][29]
Societies speaking proto-Shona languages first emerged in the middle Limpopo River valley in the 9th century before moving on to the Zimbabwean highlands. The Zimbabwean plateau became the centre of subsequent Shona states, beginning around the 10th century. Around the early 10th century, trade developed with Arab merchants on the Indian Ocean coast, helping to develop the Kingdom of Mapungubwe in the 11th century. This was the precursor to the Shona civilisations that dominated the region during the 13th to 15th centuries, evidenced by ruins at Great Zimbabwe, near Masvingo, and by other smaller sites. The main archaeological site used a unique dry stone architecture. The Kingdom of Mapungubwe was the first in a series of trading states which had developed in Zimbabwe by the time the first European explorers arrived from Portugal. These states traded gold, ivory, and copper for cloth and glass.[30]
By 1220, the Kingdom of Zimbabwe eclipsed Mapungubwe. This Shona state further refined and expanded upon Mapungubwe's stone architecture. From c. 1450 to 1760, the Kingdom of Mutapa ruled much of the area of present-day Zimbabwe, plus parts of central Mozambique. It is known by many names including the Mutapa Empire, also known as Mwene Mutapa or Monomotapa as well as "Munhumutapa", and was renowned for its strategic trade routes with the Arabs and Portugal. The Portuguese sought to monopolise this influence and began a series of wars which left the empire in near collapse in the early 17th century.[30]
As a direct response to increased European presence in the interior a new Shona state emerged, known as the Rozwi Empire. Relying on centuries of military, political and religious development, the Rozwi (meaning "destroyers") expelled the Portuguese from the Zimbabwean plateau in 1683. Around 1821 the Zulu general Mzilikazi of the Khumalo clan successfully rebelled against King Shaka and established his own clan, the Ndebele. The Ndebele fought their way northwards into the Transvaal, leaving a trail of destruction in their wake and beginning an era of widespread devastation known as the Mfecane. When Dutch trekboers converged on the Transvaal in 1836, they drove the tribe even further northward, with the assistance of Tswana Barolong warriors and Griqua commandos. By 1838 the Ndebele had conquered the Rozwi Empire, along with the other smaller Shona states, and reduced them to vassaldom.[31]
After losing their remaining South African lands in 1840, Mzilikazi and his tribe permanently settled in the southwest of present-day Zimbabwe in what became known as Matabeleland, establishing Bulawayo as their capital. Mzilikazi then organised his society into a military system with regimental kraals, similar to those of Shaka, which was stable enough to repel further Boer incursions. Mzilikazi died in 1868; following a violent power struggle, his son Lobengula succeeded him.
In the 1880s, European colonists arrived with Cecil Rhodes's British South Africa Company (chartered in 1889). In 1888, Rhodes obtained a concession for mining rights from King Lobengula of the Ndebele peoples.[32] He presented this concession to persuade the government of the United Kingdom to grant a royal charter to the company over Matabeleland, and its subject states such as Mashonaland as well.[33] Rhodes used this document in 1890 to justify sending the Pioneer Column, a group of Europeans protected by well-armed British South Africa Police (BSAP) through Matabeleland and into Shona territory to establish Fort Salisbury (present-day Harare), and thereby establish company rule over the area. In 1893 and 1894, with the help of their new Maxim guns, the BSAP would go on to defeat the Ndebele in the First Matabele War. Rhodes additionally sought permission to negotiate similar concessions covering all territory between the Limpopo River and Lake Tanganyika, then known as "Zambesia".[33] In accordance with the terms of aforementioned concessions and treaties,[33] mass settlement was encouraged, with the British maintaining control over labour as well as over precious metals and other mineral resources.[34]
