Hi there! Finally, I've completed one yearly paper. This is the trilogy to the 2019 Paper - the MCQ video tutorial. In this paper, I observed that there are many questions that require you to identify the incorrect / false statements. So do take note. The tougher questions are 25, 28, 29, 32, 33, 37. Do try them on your own before checking your answer, so you could experience the rigor of the paper. O level Sci Chem - 2019 MCQ If you are looking for all the video tutorial for the year 2019, here's the remaining sections: O level Sci Chem - 2019 Section A O level Sci Chem - 2019 Section B “Education is the passport to the future, for tomorrow belongs to those who prepare for it today.”  — Malcolm X Till next time!

Hi there, The three final questions in 2019 Paper is here. Due to technical error, I have to recorded myself twice, so here are the 2 video tutorial: O level - Sci Chemistry - 2019 - Q8 a and b O level - Sci Chemistry - 2019 - Q8c onwards Enjoy! “You’ve got to get up every morning with determination if you’re going to go to bed with satisfaction.” – George Lorimer Till next time!

Howdy! I hope the video tutorials have been helpful for you. This post will link you to the topic on Salts. In 2019, in the Combined Science paper, there was a 4-marks structured question on describing the preparation of sodium sulfate . If you paused for a moment and think about the above question, would you be able to a) state the preparation method? b) write out the step-by-step procedure? Meanwhile, here is the video link to the Pure Chemistry  Topical TYS - SALTS  questions. “Strive for progress, not  perfection.” – Unknown Till next time!

Hi there, This is the video tutorial of the 2019 paper, Section A. Concepts being tested here include: Atomic structure - relative mass and relative charge of sub-atomic particles Organic chemistry (Alkane, Alkene reactions)  Separation Technique (fractional distillation)  Kinetic Particle Theory (arrangement and movements of solid and gas)  Mixture vs Compounds  Speed of reaction (drawing graph and explain the shape of graph)  Writing chemical formula  Video link:  2019 Sci Chem - Section A “Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.” – Thomas A. Edison Till next time! 

Good morning good morning, Two topics coming right up in this post! A summary of popular questions based on the topics: Elements, Compounds and Mixtures Distinguishing the diagrams for elements, compounds, mixtures Note: Elements can exist as atoms / molecules [Refer to question 1, diagram R and S respectively] Common examples of mixtures - air, crude oil / petroleum / seawater / alloys e.g. brass, steel Good to know: the definition of elements, compounds, mixtures as it will guide you towards identifying them.  Video tutorial for elements, compounds, mixtures:  N level Sci Chem - Elements Compounds Mixtures Atomic Structure  The three subatomic particles and their relative charges and approximate relative massess.  'Location' of the three  subatomic particles. Define isotopes and describe similarity / differences in given isotopes (See Section B, question 1)  Writing electronic configuration, drawing electronic structure...

Good (extra) morning, The end of circuit breaker is around the corner and I have been training myself to wake up earlier than usual to get ready for school reopen. I hope you are geared up for school, after all, you have not seen your friends for the past two months! So in today's post, I've put together the video link for the first three topics. A summary of popular questions based on the topics: Experimental Technique Identifying apparatus based  on given diagram  Accuracy of apparatus (measuring cylinder, burette, pipette) note: burette measures to the nearest 0.1 cubic metre; the burette reading is accurate to 0.05 cubic metre e.g. 22.70, 24.65  Video tutorial for experimental technique:  N level Sci Chem - Experimental Technique Methods of Purification  Identify the set-up for the various method of purification  Identify the states of matter based on given melting and boiling points.  Chromatography - reading the results o...

Howdy! I'm feeling driven to get the Loom videos ready so I could journey with you towards your national examination. I hope you have been good. Today resource on metals and there are a total of 31 MCQ questions for the last ten years. If you do a quick math, that is an average of 3 metal-related MCQ per year. This year, there could be more because the one full section on Organic Chemistry has been removed from your testable syllabus. More information on  Syllabus 5106 Year 2020 A summary of this chapter popular question includes: Structure of alloys  General properties of metals (take note: Group I metals - Alkali metals do not behave like conventional metals) Advantages of recycling  Conditions for rusting, especially how oxygen gas is used up and water level in a set-up will rise accordingly)  Reactivity of metals (based on observation of reactions, with water, with steam, with carbon)  Blast Furnace  A breakdown on the weightage o...
