IB Diploma chemistry guide 2019-2020

IB Diploma chemistry guide 2019-2020

You can download IB diploma chemistry guide from the above link.

This is for the students of IB diploma from the 2016 first exams on wards till now.

It is highly recommended for IB Diploma chemistry students to regularly go through the chemistry guide so that you are aware about the syllabus content which is coming in your exams. Students and teachers sometimes ignore the guide which lend them in a time wasting exercise. For example, earlier the working and structure of mass spectrometer was in IB diploma syllabus but now it is not in syllabus so if you are still preparing about the structure and working of mass spectrometer, you are wasting your time. Only the % abundance of isotopes is in syllabus now. 
So to avoid this situation, you should go through the chemistry guide.

Chemistry data booklet for IB latest

Chemistry data booklet for IB latest 


Latest Chemistry data booklet for IB diploma chemistry students is of fourth edition and it is for the 2019 and 2020 final IB Diploma students. It is in use since 2016 examinations. Students often uses old data booklets which is not suitable for the latest IB questions as they write to reffer on a particular table number which is not similar in old and new data booklet.
Students should also focus on the content of data booklet because if you are familiar about what is already given in the data booklet, you need not to mug it up.

Internal Assessment
The internal assessment task worth 20% of the final assessment will be one scientific investigation taking about 10 hours and the write up should be about 6 to 12 pages long.
The IA can be
a hands-on laboratory investigation,
using a spreadsheet for analysis and modelling,
extracting data from a database and analysing it graphically producing a hybrid of spreadsheet/database work with a traditional hands-on investigation,
• using a simulation provided it is interactive and open-ended.

Assessment in IB year 12: Regular assessment will take place using various formative and summative assessment methods.
Final Assessment at the end of IB Year 13.
Paper 1 (Weighting: 20%)– Multiple Choice – 45 minutes (30 marks). A calculator is not allowed for this paper.
Paper 2(Weighting: 40%) – Written Paper – 1 hour 15 minutes (50 marks). A calculator is allowed for this paper, you will also be provided with a data booklet.
Paper 3(Weighting: 20%) – Scientific Skills and the Optional Module – 1 hour (35 marks)
IA: 20 %
