Questions testing these objectives will begin with one of the following words; predict, suggest, construct, calculate or determine.
C Experimental skills and investigations Students should be able to 1 2 3 4 5 6 plan investigations; use techniques, apparatus and materials; make and record observations, measurements and estimates; interpret and evaluate observations and experimental results; select techniques and materials; evaluate methods and suggest possible improvements.
Candidates will be required to answer a total of six questions, two from Section A one from Section B, two from Section C, plus any other. Paper 2 1h 48 marks A variable number of structured questions, all compulsory. Based on the core syllabus Section 1 to Answered on the question paper.
Paper 3 1h 40 marks Forty multiple choice questions based on the core syllabus Sections 1 to Thirty items will be of the direct choice type and ten of the multiple completion type.
All questions will include 4 responses. Paper 4 1h 40 marks Testing the options.
Three questions on each option 10 marks each. Candidates to answer a total of four questions, not more than two on any option. Duration 2h 1h 1h 1h 2h Marks 72 48 40 40 50 Paper 5 2h 50 marks The scope of the practical test is indicated in the Practical Chemistry syllabus.
The paper will be marked out of 75 and scaled to a mark out of Theory Papers Papers 1, 2 and 3 marks in total Knowledge with understanding approximately 55 marks allocated to recall and 35 marks allocated to understanding.
Handling, applying and evaluating information approximately 70 marks. The portion of marks allocated to Physical, Inorganic chemistry in Papers 1, 2 and 3 will be in the approximately ratio Step 3 Write notes that address the syllabus sentence from the relevant resource sections.
Note that there is often some extra contextual information that may be gathered from the textbook and notes. The ideal gas is merely a theoretical construct, and no such gas exists in real life.
However, many real gases exhibit behaviour which approximates to an ideal gas. The assumptions of the kinetic theory as applied to an ideal gas are as follows: Gas particles atoms or molecules are constantly in random motion in straight lines.
There are negligible intermolecular forces of attraction between gas molecules. Collisions between gas molecules are perfectly elastic. The gas molecules occupy a negligible volume relative to the volume of a container. B it is always useful to draw rough diagrams for concepts in chemistry.
Step 4 Now to study and memorise your notes. The most efficient and powerful way to memorise is through practice recall. To do this, simply read the syllabus sentence, and try to recall the points, equations and diagrams you made in the notes. Step 5 Once you know the content well, and attempt some practice questions as well as referred to marking schemes for these, you may come across keywords or facts that you must have in your answer to get the marks.
Point 3 now becomes: Collisions between gas molecules are perfectly elastic, i. The CIE website itself hosts a whole lot of chemistry past papers that you can use in your study - find them here.
You can also find past papers on XtremePapers. How to Use Chemistry A Level Past Papers For all these papers, practising questions after you have a strong knowledge base is crucial to understand how to answer questions, and you can locate past papers for each of the five on the CIE website link shared above.
The first number of the paper e. Make sure the syllabus code is correct.
S or W mean summer or winter series. These are vital to get to know which keywords and style of answers the examiners are after! The Data Booklet, of which a specimen can be found here , is a short booklet which accompanies the question paper in every exam.
It contains information including the periodic table, i.
The following sample A Level Chemistry question will demonstrate how the data booklet could be used. Final Thoughts A Level Chemistry is often regarded as one of the more difficult subjects due to sheer breadth of content.
However, although A Level Chemistry seems daunting, there is no need to fear. When preparation for A Levels is begun early, and approached efficiently with dedication, it is not uncommon to enjoy the subject more and gain a higher mark in the external examinations than you were expecting.
