Berry Berry Teacher was surfing around the net to look out for like minded teachers with resource sites to help student. So in the midst of surfing the internet, filtering spam sites, identifying good sites and finding the best of the resourse sites for student, I have come across two certified berry good sites which all students should also visit in addition to Berry Berry Easy.
The other two sites which are shown in the Berry Link sidebar are:
- Cikgu Naza’s blog - Resources are available for science and mathematics subjects for Form 1-5 (Malaysia Education System).
- Cikgu Nurul’s blog - Resources are available for PMR science subjects.
Berry Berry Teacher wants to recommend all students to bookmark the two recommended sites in addition to up-and-coming, newly established Berry Berry Easy
How to Score A(s) in SPM Chemistry (3 Berry Berry Easy Level) : MPM
October 30, 2009
Here are some tips from the Berry Berry Teacher on:
How to Score A(s) in SPM Chemistry (3 Berry Berry Easy Level) : MPM
M – Memory level: You must memorise the 3 important notes in Chemistry Kung Fung Manual which is ‘formulae of common cations and anions’; ‘reactivity series’ and ‘periodic table’ and try to make it as your pocket notes. View your pocket notes everyday! Then construct the empirical formula of various ionic compounds.
P – Practice level: You must practice some calculation questions on Mole Concept and Molarity (solution). Besides that, you MUST attempt some SPM past year papers and other states’ trial papers*. It is important for you to familiarise the ‘pattern’ of the SPM questions. Try to get few friends to practice the questions together (form study groups). It will save a lot of time in revision if everybody chips in.
M – Mastery level: You must be able to write chemical equation and balanced them in the equation. You will love it because it is so berry berry easy! Next, try to pay more attention during experiment sessions (PEKA). It is important for you to get ‘perfect score’ in Paper 3 (The berry berry easy paper in Chemistry Paper). Berry Berry Teacher also recommends you to prepare reports on extra experiments (beside the PEKA experiments that your teacher insisted on you to hand in). It will help you in writing the essay (Q3 – P3).
After reading these notes, you will find that Chemistry is a Berry Berry Easy subject to learn and you will definitely score A in SPM Chemistry!

How to Score A(s) in SPM Biology (3 Berry Berry Easy Level) : MMM
“In Biology, the MMM method will be needed to score A. What is the MMM method that Berry Berry Teacher recommends? To use this method to score A in SPM Biology, you will be needing a high memory capacity and passion towards this Berry Berry Easy subject. With Berry Berry teacher’s tips, you will definitely score A in SPM Biology. Biology is a subject that needs a lot of memorisation in the structures, processes and concepts. Berry Berry big memory capacity!“ – Berry Berry Teacher
M – Memory level: You must memorise the structures and mechanisms, from a simple cell structure to the most complicated anatomy structure. Besides that, the heart structure and blood circulation are important topic that you must memorise too! Try to visualize the process (or you can try to find some interesting video online).This will help you in paper 2 (essay) which requires you to explain the processes and methods.
M – Maintained level: You must maintain your memory level at the highest level by writing out important data and keywords repeatedly (as many time as possible). The best method would be to get more sample essays and start to memorise it everyday. Try to get few friends to prepare important notes. It will save a lot of time in the preparation of Biology notes and free up more time for your revision.
M – Mastery level: You must find important keywords. Start practicing from keywords for the essays (P2). Write essays regularly. If possible, an essay per day. You will definitely score an A in SPM Biology. Besides that, you must also master the food testing experiment, respiration mechanisms, blood circulation and digestion. The aforementioned topics are the few Berry Berry Important Topics that you must maste.
After reading these notes, you will find that Biology is a Berry Berry Easy subject to learn and you will definitely score A in Biology!

This is a list of your berry important definitions for STPM Form 6 Chemistry. Sometimes the easiest way to understand and remember essential definitions and technical terms is to constantly recite it with your friends and question each other. So spread the word to your friends about this post and recite the definitions together.
STPM Chemistry Form 6 Definition List:
- The Hund Rule – orbital with the same energy level (degenerate orbitals), electron will occupy different orbital singly/one electron first with the parallel spin, before pairing.(Reject: same spin, spin with same direction) STPM 2008, 2007
- Pauli Exclusive Principle – Each orbital can hold a maximum of two electrons with opposite spin. (Reject: different spin) STPM 2007
- Aufbau principle – Electrons occupy orbitals with the lowest energy level first. (Reject: occupy lower energy first) STPM 2006, 2007
- Vapour pressure – the pressure exerted by a vapour that is in equilibrium with its liquid at a fixed temperature in a closed system. It is due to the collision of the vapour particles on the walls of the container. STPM 2004
STOICHIOMETRY
- Molarity (M) [concentration of a fluid solution] – defined as the moles of a solute per volume of solution.
- Density [concentration of a fluid solution] – defined as the mass of solution per volume of solution.
