IBDP Biology
The overview is going to help you understand how imperative it is to understand the meaning of Biology in explaining the diversity of living species-either micro or macro. The inventions and innovations in research is making the science walk its progressive steps in the face of growing pressure on the population and the environmental system. The study of Biology belongs to Group 4 ‘Sciences’ of the BPDP curriculum. The study of life and living cellular organisms owes its origin from two Greek words- ‘bios’ meaning life and ‘logos’ meaning study.

Can't Complete this
Through nature’s intrinsic selective discretion of differential survival and reproduction of life due to the differences in their phenotypes, over a period of three billion years we have almost more than eight million species on earth.
The word “biology” was coined by German naturalist Gottfried Reinhold in 1802 but our comprehension of life started with the advent of technology in the C18th and C19th.
The thread of life is spun with cell as the basic unit of life at one end and the complete functionalities of ecosystem with the behavioural traits of predator and prey at the other end.
Here, I would help you understand the significance of IBDP Biology, the aims and objectives, the teaching and learning hours for HL/SL, the math involved in study the subject, and the tips to ace the exam with the perfect 7.
Remember, experimental sciences can be best understood by open-minded individuals with the help of a sequential process adopted in research. Starting from collecting facts and figures, to representing them so as to frame your hypothesis, substantiating with expected and actual observations, claims, and counter claims, and finally arriving at a conclusion just don’t end the process. As IB learners you develop an open-minded global perspective to allow a provision for community analysis and feedback.
Aims and objectives of IBDP Biology curriculum HL/SL
With the use of science and technology you get to construct knowledge, apply, analyse, and critically evaluate the scientific information. You get to understand the impact of scientific disciplines on other areas of knowledge, which clearly indicates your trans-disciplinary integration skill.
Is there any Math involved in IBDP Biology?
It’s a prerequisite that the IBDP Biology candidates would be knowing the basic mathematical operations, methods of data collection, organization, presentation and interpretation with the help of hypothesis testing based on the confidence interval of the parameter. Concepts like t-Test, Chi-squared distribution, Standard Error in Excel need to be acquired as a part of the learning process.
Instruction hours of IBDP Psychology HL/SL
The core is common for SL and HL, however, there is a greater depth of study in HL when it comes to additional higher level (AHL) and in the common options. The core is handled for 95 instruction hours, each for HL and SL. The AHL is for 60 additional hours exclusively for HL. Also, the optional topics are dealt with for 25 hours in HL and 15 hours in SL. The component of Practical scheme of work (60 hours for HL and 40 for SL) has three parts-practical activities (40 hours for HL, 20 hours for SL), internal assessment/ IA (individual project of 10 hours for each HL and SL), and the Group 4 project (10 instruction hours for each HL and SL). The cumulative number of instruction hours for SL is 150, while for HL it is 240 hours. Prior knowledge is not a prerequisite to study the coursework at the SL, however, it’s needed to study at the HL.
How to ace IBDP Biology with a perfect 7?
IBDP Biology is the third most demanding subjects based on the statistic of 2020 shared by the IBO. If you look at the facts and figures, you would see that on a scale of 1-7, the perfect 7 is bagged by only 9.7% of the takers. However, there is a vast disparity between the number of scorers with a 6 and a 7. In fact, the percentage of scorers with a 5 is the highest. So, it’s evident that a bit harder effort with the right approach would surely help you to ace the IBDP Biology exam with the perfect score. The approach indicates your daily planner, understanding the assessment criteria, strategies of response, solving revision packs, brushing up the comprehensive syllabus through a crash course would surely help.
Always remember that IB is not only a curriculum but more of a methodology, which requires a prescribed approach to be adopted for a successful completion. Don’t hesitate to resort to helps from IB tutors and examiners at the right time, if required. Now that the IB online learning platform is quite expansive, transparent, and accessible irrespective of any geographical boundaries, getting the most desired hand holding is not at all difficult. However, never keep the doubts pending till the last minute. The earlier your doubts are sorted out, the better you are.

Overview of Biology and its nature of science
The name says it all
The study of Biology belongs to Group 4 ‘Sciences’ of the BPDP curriculum. The study of life and living cellular organisms owes its origin from two Greek words- ‘bios’ meaning life and ‘logos’ meaning study.

The thread of life is spun with the cell as the basic unit of life at one end and the complete functionalities of the ecosystem with the behavioral traits of predator and prey at the other end.
The approach to teaching
It is experimental with a good hands-on in connecting lessons with real life observations. The order in which the syllabus is tailored might not necessarily be the other of teaching in the classroom, which is finally the subject matter expert’s discretion.
What’s the difference between SL and HL?
The core is common for SL and HL, however, there is a greater depth of study in HL when it comes to an additional higher level (AHL) and in the common options.
Prior knowledge is not a prerequisite to study the coursework at the SL, however, it’s needed to study at the HL.
For SL the number of instruction hours is 150, while for HL it is 240 hours.
The trans-disciplinary integration
Biology and Mathematics
It’s a prerequisite that the biology candidates would be knowing the basic mathematical operations, methods of data collection, organization, presentation and interpretation with the help of hypothesis testing based on the confidence interval of the parameter.
Biology and ICT
It’s quite obvious that ICT has a nexus with interpretation of ideas of our daily life.

Apply the science and technology involved in research
Analyse, imbibe, assimilate and synthesize the results of the findings
Recognize the inter-connection between biology and other disciplines
Connect science with technology, analyse its possibilities and limitations
appreciate scientific study and creativity within a global context through stimulating and challenging opportunities.

Assessment
Forms of assessment (EA and IA)
Assessment is integral to the teaching and learning approaches. There are two forms of assessment-external (EA) and internal (IA). EA is assessed by the IB examiners, while IA is assessed by teachers and externally moderated by the IB.
Types of assessment-Formative and Summative
There are two types of assessment identified by the IB- Formative and Summative.
Formative assessment is kind of a progress tracker for the students and the teachers highlighting on the solidity of foundation in the understanding and the applications of the skills.
Summative assessment assesses the progression of the students’ understanding from known to unknown.
Assessment criteria –mark bands and level descriptors for open-ended questions
- Each criterion focuses on the skill to be demonstrated by a student.
- Each criterion has a hierarchy of level descriptors, ranging from lower to higher order thinking.
- Each descriptor is worth of one or more marks, where the maximum marks to be allotted depends upon the importance of the criterion.
- Each level descriptor corresponds to a range of marks used in order to differentiate student performance.
- The marks awarded for each criterion is cumulatively added to assign the total marks for a piece of work.
