Teknik Menjawab Soalan - Describe Eutrophication Process (UPDATED FOR SPM 2017).

*This post was originally posted back in 2013. I realized one of the trial question 2017 asked about eutrophication. So, I'm digging old treasures just for you SPM 2017 sitters.

1. Eutrophication is one of the most famous question for Biology SPM.

Download the rest of the question here.
To answer the question above, I give you technique to answer it by using FADDDDD ( 1 F & 5 'D's).

2. The FADDDDD outline:

3. The specific question for this FADDDDD would be about the process & consequence of eutrophication. Let's discuss what are the initials in the FADDDDD:

F - Fertilizers
A - Algal bloom
D - Die (submerged plants)
D - Die (aquatic life aka fishes)
D - Die (alga itself!)
D - Decomposition
D - Dead zone

4. The FADDDDD is favorable as it covers all important points needed for full marks (terms, explanations/processes, & examples - remember PEE system in my previous posts). Below is the example of a good answer from an A-list student:


Q: Discuss the eutrophication process which leads to a high BOD in an ecosystem. 

Answer Outline:

The answer is given full marks (nearly 100%) because it contains these important points:

1. Can you see the red bold words? Those are the important terms (istilah) enlisted as FADDDDD.
2. Can you see the blue bold words? Those are the right examples.
3. Can you see the red-underlined sentences? Those are the correct explanations.



SPM 2017 TRIAL QUESTION ANALYSIS - Role of Exercise to Lymphatic System

1. Let's observe the pic below:

2. A typical couch potato. This prolonged state could be detrimental to his lymphatic system.

3. This is because the lymph cannot be pumped properly by the skeletal muscle contraction. We can say this since the person is not physically active. So, this person needs a regular exercise.

4. We can use this info to answer a short trial question in Paper 2:

5. HINT: Read the questions carefully and find the key points (circled ones). Write down your answer in short, concise sentence. Don't forget the conjunctions! (so, as a result).

1. GMO food, they are everywhere! Just look at the big fat KFC drumsticks...

2. We all know the importance of trial questions since the real SPM questions would be based on them. Let's discuss one question from a trial paper for MRSM:

Credit goes to Bumi Gemilang.

3. The question is quite straightforward, which we need to elaborate the benefits and risks of GMO food

4. Remember, this is a discussion-type question which asks about some biotech application (in this case, genetics applied in GMO production).

5. Critical: So, you need to put intro, conclusion, PEE schema (Point-Explain-Example), and lots of conjunctions (firstly, secondly, besides, also, as a result, etc...).

6. So, here are my proposed answer outline which will guarantee you a perfect 10-mark score:


P/S: This will be my last post for this month since I'm going away to schools all over M'sia for seminar tour. Take care all!

6 Highly Useful (& Fast+Easy+Free) Tips to Improve your Biology in 1 Month.

SPM is here again. Students might feel the dread since there are too many notes to read in too little time. Fortunately, there are ways to improve your Biology score. They might not get you A, but at least your result will improve significantly if you do this. Here are the 6 tips:

1. Study with your Friends.
Plan a study group with your friends. Teach your friends one chapter and ask them to teach your another. Nothing is more motivating (and fun!) than studying together. 

2. Do Past Year Questions.
Most of SPM questions tend to repeat themselves from year to year So, it's better for you to be familiar with them. So, get yourselves some past-years questions from your nearest bookstore, pronto.  

3. Do the Trial SPM Exam Questions.
Most seminars speakers proclaimed that their forecast questions would come out in the exam. There is nothing miracle about it. This is because most SPM questions are mostly based on these trial exams from various schools/states. So, get yourselves some by downloading the questions online through various academic sites.

4. Do Topic-by-Topic Questions
SPM is all about familiarizing yourselves with the questions. Do this unceasingly. You will realize the questions tend to repeat themselves. By that time, the good results are already yours.

5.Read Compact Notes.
You no longer have the time to comprehend the whole notes. Instead, you should understand the critical points, which are frequently asked in the exam. You can read from various books/ online notes.

6. Read Biology Notes from Cikgu Heery.
What are you waiting for?

TEKNIK MENJAWAB : Gastric Bypass Procedure (UPDATED FOR SPM 2017)

KBAT question is not about new, hard, difficult, or unusual topics. It's about text-book topics being asked in different perspectives. Here, we shall discuss the GBP, which the basic features we already learnt  in F4 in Nutrition chapter:

Let's revise the concept from Nick and Singer below...

Easy enough. Now we can go straight to the KBAT question examples:


Let's analyse the answers:

Question 1: Full marks are given because the student has given the answer according to the question (physiological and physical). (That's why you need to read the question carefully!).

Question 2: Full marks are given due to relevant (logical) answers.

Question 3: Again, full marks are given because the student has given the answer according to the question (regarding the digestion system).

Question 4: Again, full marks are given due to relevant (logical) answers + relevant reason.


If you see my answers, they are rather short and concise. Yup, that's the gist of SPM essay writing. So, keep your answer short and simple. Just remember this : One sentence = one relevant point = one full mark.
