[J2] Lesson 32 (COE + DC Grade A Lesson 2 + P&C + Probability L2 + Solubility Equilibrium)

[J2 Physics PMCians] Electricity & DC Circuits (Grade A) – Part 2


What we did in 2 hours:

This week, students attempted Structured Questions on circuits, with emphasis on using data from graphs to calculate our answers. We also looked more in depth at the drift velocity of electrons and what it means. 

What you take home:

Electricity Grade A Test 3 (solutions)

For your reference only.  



Electricity Grade A Test 4 (solutions)  

For your reference only.


Special Mention:

In our next lesson, we will move on to Grade A Simple Harmonic Motion (SHM) questions.

Wishing everyone a wonderful National Day celebration, and a blessed time with your loved ones!


From you friendly tutors,

Mr Sim & Mr Kwok 🙂

What we did in 2 hours:

We finished our revision on Discrete Random Variables and Binomial Distribution. On top of all the basic conditions and techniques, we went through standard question types and variations. Do note the special types in Secrets Enclosed, which we also practised, as they are quite popular Grade-A style setting these days!

What you take home:

Worked solutions for Q6 and Daily Dose are linked here:



Weekly Quiz: Quiz E and Solutions for Quiz D have been updated into the link.


Special Mention:

This week, we finish the final questions of Binomail & DRV and move on to Normal Distribution.


See You and Stay Healthy!

[J2 Chemistry PMCians] Saying goodbye to Organic Chemistry!


What we did in 2 hours:

We bade farewell to Organic Chemistry revision by completing our revision on Amino Acids + Proteins. We moved our revision back to Solubility Equilibria, where we discussed the calculations involving solubility and Ksp, the common ion effect as well as complex ion formation and how they affect our equilibria.

What you take home:

The solutions to the Homework questions on Acidity, Basicity and Hydrolysis of Organic Compounds is found here:


Special Mention:

Next lesson, we shall complete our revision on Ksp.


See you in class!
