BIO ESSAY- Answering Technique

Reposted for SPM candidates 2011

COMMON but IMPORTANT TIPS in answering BIO ESSAYS are:

1. READ THE QUESTION CAREFULLY before choosing TWO out of FOUR Qs.

2. HIGHLIGHT the COMMAND word in the question such as Explain, Describe,Compare...so that you know what you are supposed to do..

3.Plan your ESSAY...(by roughly sketching mind map, flow chart, diagram etc )

4.LOOK at THE MARKS allocated.(This give you idea how long your essay should be )

5.Answer in paragraphs if it is a long essay.

6. Tables are allowed only for COMPARING

7.Write at least 2 pages (including half page of Diagram) -

8. Produce Diagram to support your answer but make sure it is all labelled!!

9.Give Facts + Explanation for every answer..

10.Write as long as you like..Never mind if it is wrong..you wont be penalize.

11. Do not write in a point form...because it is ESSAY !!!

12.Choose only TWO essays if the instruction is TWO!!

13.....Write and keep on writing.....Produce all the BIO facts that you ever remember.

( BIO PAPER 2 need you to master BIO CONTENT very well !)
