SPM Biology Analysis 2015

Paper 2 (Section A: Structure) There are hot topics for SPM 2012 Papers

4551/2. In this question paper consists of two sections: Section A & B.

In Section A, there are 5 questions (Question number 1 to 5) and students

needed to answer all questions. On the other hands, students need to

answer any two questions (Question number 6 to 9) from Section B.

Students are advised to spend 90 minutes to answer questions in Section

A and 60 minutes for Section B. (Total marks = 100)

Section A consists of 5 structured questions where you must answer all

questions while Section B consists of 4 essay questions where you can

choose any 2 of them. You can answer extra questions in Section B if you

have time. The examiner will mark all questions and choose the questions

where you score the highest marks.

When answering, read the question and all information given carefully.

Make sure that you know what the question is asking for. Answer the

questions based on your knowledge and understanding on the relevant topic

in Biology. Certain questions may test you on more than one topics. For some

questions, you may have to apply what you have learnt in Biology in order to

answer them. You have to think carefully and relate the question to what

you have learnt. You may also be asked to give your own opinions.

When writing your answer, you can use the same or similar words or

sentences as those in revision books if possible. However, sometimes you

may need to make some changes in order to suit the question. You can also

answer in your own sentences that have the same meaning. If the question

asks on something that is not in revision books (the question requires you

to apply what you have learnt in Biology or give your own opinion), then you

have to answer in your own sentences. For all questions, your answer must

be specific and not too general. Give the most suitable answer according to

the question.

You should use the correct Biological terms in your answer. Do not replace

them with other terms that are inappropriate, even if their meaning are

the same. The spelling for all Biological terms must also be correct,

otherwise marks may be deducted. For other non-Biological terms, marks

is not deducted for wrong spelling. If your make grammatical errors in your

answer, marks will not be deducted as long as the examiner can understand

what you are writing. Do not use any short forms in your answer, except

when writing units for quantities. For all chemical substances, you should

write the complete name and do not write only the chemical formula.

It is not compulsory to answer in continuous writing form. You are allowed

to answer in table form or other suitable forms. In suitable cases, you can

also use diagrams, equations or graphs in your answer. However, you are not

advised to answer in point form. There is not penalty for answering in point

form, but some inexperienced examiners may deduct your marks if you do

so.

When answering questions on calculation, you must show all workings. You

should not skip any important steps, otherwise marks may be deducted. You

must also write the correct unit for the final answer. The number of marks

allocated for the question usually shows the amount of working needed. 1

mark will be given for each important step and the final answer. You are

not allowed to write extra solutions or answers. If you do so and any of the

answers or solutions is wrong, marks will be deducted. For a calculation

question which requires you to use your answer from the previous question,

even if your answer for the previous question is wrong and you use it for

this question causing your answer for this question to be wrong, usually you

will still get full marks for this question as long as your calculation for this

question is correct. This is known as 'error carried forward'.

For questions that require explanation or description, your answer must be

very detailed. You are advised to answer in complete sentences so that your

answer can be easily understood. The number of marks allocated for the

question usually shows the number of points needed in your answer. 1 mark

is given for each correct point. Do not miss out any important points in your

answer. You are allowed to write extra points in your answer, but you must

be careful not to write points that contradict one another. Marks will only

be given for the correct points. For points that are not acceptable,

whether they contain wrong facts or not, no mark will be given or deducted.

However, for points that contradict one another, no mark will be given for

both the points, even if one of them is correct. You are advised to write

extra points if you are not completely sure of what the question is asking

for.

For questions that do not require explanation or description, write the

answer straight away. You need not answer in complete sentences. The

number of marks allocated for the question usually shows the number of

answers needed. If the question states the number of answers you have to

write, then you are not allowed to write extra answers. If you do so and

any of them is wrong, marks can be deducted. If the question does not

state the number of answers you have to write, you are allowed to write

extra answers, but you must be careful not to write answers that

contradict one another. Marks will only be given for the correct answers.

For answers that are not acceptable, whether they contain wrong facts or

not, no mark will be given or deducted. However, for answers that

contradict one another, no mark will be given for both the answers, even if

one of them is correct.

When plotting graph, draw both the horizontal and vertical axis on the

graph paper correctly. Label both axis correctly and state the unit (if any).

Use a suitable scale for both axis. Plot all points on the graph accurately.

Then, if it is possible to draw a curve or straight line that passes through

all points on the graph, you should do so. If it is not possible, you can just

use straight lines to join them point-to-point. The graph should cover at

least half of the graph paper.

When drawing diagrams, make sure that all important details are included

in the diagram you draw. You have to label correctly all parts in the diagram.

Your diagram should be clear and neat.
