So, when a student is trying to solve IGCSE Topic questions, he should get questions from the smallest of topics. So, for  instance, suppose, he is learning the topic say Reproduction, in which he studies the following topics:

16.1 Asexual reproduction


1 Describe asexual reproduction as a process resulting in the production of genetically identical offspring from one parent

2 Identify examples of asexual reproduction in diagrams, images and information provided Supplement

3 Discuss the advantages and disadvantages of asexual reproduction: (a) to a population of a species in the wild (b) to crop production

16.2 Sexual reproduction


1 Describe sexual reproduction as a process involving the fusion of the nuclei of two gametes to form a zygote and the production of offspring that are genetically different from each other

2 Describe fertilisation as the fusion of the nuclei of gametes Supplement

3 State that nuclei of gametes are haploid and that the nucleus of a zygote is diploid

4 Discuss the advantages and disadvantages of sexual reproduction: (a) to a population of a species in the wild (b) to crop production

16.3 Sexual reproduction in plants

Core 1 Identify in diagrams and images and draw the following parts of an insect-pollinated flower: sepals, petals, stamens, filaments, anthers, carpels, style, stigma, ovary and ovules

2 State the functions of the structures listed in


3 Identify in diagrams and images and describe the anthers and stigmas of a wind-pollinated flower

4 Distinguish between the pollen grains of insect-pollinated and wind-pollinated flowers

5 Describe pollination as the transfer of pollen grains from an anther to a stigma

6 State that fertilisation occurs when a pollen nucleus fuses with a nucleus in an ovule

7 Describe the structural adaptations of insect-pollinated and wind-pollinated flowers

8 Investigate and describe the environmental conditions that affect germination of seeds, limited to the requirement for: water, oxygen and a suitable temperature


9 Describe self-pollination as the transfer of pollen grains from the anther of a flower to the stigma of the same flower or a different flower on the same plant

10 Describe cross-pollination as the transfer of pollen grains from the anther of a flower to the stigma of a flower on a different plant of the same species

11 Discuss the potential effects of self-pollination and cross-pollination on a population, in terms of variation, capacity to respond to changes in the environment and reliance on pollinators

12 Describe the growth of the pollen tube and its entry into the ovule followed by fertilisation (details of production of endosperm and development are not required)

16.4 Sexual reproduction in humans


1 Identify on diagrams and state the functions of the following parts of the male reproductive system: testes, scrotum, sperm ducts, prostate gland, urethra and penis

2 Identify on diagrams and state the functions of the following parts of the female reproductive system: ovaries, oviducts, uterus, cervix and vagina

3 Describe fertilisation as the fusion of the nuclei from a male gamete (sperm) and a female gamete (egg cell)

4 Explain the adaptive features of sperm, limited to: flagellum, mitochondria and enzymes in the acrosome

5 Explain the adaptive features of egg cells, limited to: energy stores and the jelly coat that changes at fertilisation

6 Compare male and female gametes in terms of: size, structure, motility and numbers

7 State that in early development, the zygote forms an embryo which is a ball of cells that implants into the lining of the uterus

8 Identify on diagrams and state the functions of the following in the development of the fetus: umbilical cord, placenta, amniotic sac and amniotic fluid


9 Describe the function of the placenta and umbilical cord in relation to the exchange of dissolved nutrients, gases and excretory products between the blood of the mother and the blood of the fetus

10 State that some pathogens and toxins can pass across the placenta and affect the fetus

16.5 Sexual hormones in humans


1 Describe the roles of testosterone and oestrogen in the development and regulation of secondary sexual characteristics during puberty

2 Describe the menstrual cycle in terms of changes in the ovaries and in the lining of the uterus


3 Describe the sites of production of oestrogen and progesterone in the menstrual cycle and in pregnancy

4 Explain the role of hormones in controlling the menstrual cycle and pregnancy, limited to FSH, LH, progesterone and oestrogen

16.6 Sexually transmitted infections


1 Describe a sexually transmitted infection (STI) as an infection that is transmitted through sexual contact

2 State that human immunodeficiency virus (HIV) is a pathogen that causes an STI

3 State that HIV infection may lead to AIDS

4 Describe the methods of transmission of HIV

5 Explain how the spread of STIs is controlled


By now, you must have realised that one topic has   a large number of concepts . So your topic wise questions should give you questions on the smallest of topics.

Smart Exam Resources is the only website that gives you questions on the largest number of smaller topics that makes learning easier and less time consuming.

Secondly, we all know that the ultimate aim of any examination is to test the learner on the maximum number of concepts. In doing so, it sometimes happens that in question number 1, for instance, part a belongs to topic 1, part b, belongs to topic 2 and part 2 belongs to topic 3. So , we need topic questions that will not have irrelevant questions. For instance, if the topic is on reproduction, then it cannot have questions on plant transport in it. If it does have, then the student ends up wasting time and energy and other resources such as paper and ink. Unnecessary data , when present , only gives the user an impression, that there is so much to practice, but eventually, upon printing one realises, that most of the material is not related. 

So, to buy quality  topic wise questions, buy from smart exam resources.  And you double check, try comparing their resources, and you will see the difference in the quality, your self.

In additions, large number of past exam paper solutions are also included for theory and ATP, along with revision notes and Exam Tips and Videos and more! 

So what more can one  ask  for?


  • This page on Smart Edu Hub will  only offer you practice questions from 0610-IGCSE Biology Board Exam papers. In these papers,  the topic past paper practice questions are smartly designed in that, they have the marking schemes below the questions, thus saving on a lot of time and are ideal for board exam revision
  • Also all the questions are relevant to the latest announced IGCSE syllabus .
  • The lesson names will be as per the syllabus so that students all over the world may use it with ease even if they all use books of different authors.
  • The questions have been broken into a large number of smaller sub-topics. This will give you an opportunity to test your understanding of  the smallest of concept.
