[J2] Lesson 22 (1 – 7 June) Updates/ Debrief

[J2 Physics PMCians]Strengthening our Thermodynamic skills!!


What we did in 2 hours:

We completed our revision on Waves and Superposition, by reviewing Resolution using Rayleigh’s criterion & clarifying Stationary Waves. Kudos to all students – you’ve made a large stride in enhancing your understanding Physics!! 🙂

What you take home:

1) Superposition Solutions to resources: 

  • Superposition Round 2
  • Superposition Physics Take-Away Answers



2) Measurement Revision Resources



3) Wave Motion Daily Dose

For your personal revision. The answers and working are at the back:  



4) Superposition Daily Dose  

For your personal revision. The answers and working are at the back:   


Special Mention:

Next lesson, we will continue our Revision of Simple Harmonic Motion (SHM).

Get ready for the oscillatory motion!


Till then, enjoy a good start to school and stay safe!! 🙂

What we did in 2 hours:

Congratulations, we have completed the syllabus! 🙂


Our last part of hypothesis testing looked at questions involving unknown parameters. It’s important to identify the approach to these, where the result of the test of given, and from there work in reverse to solve for the unknown. Hypothesis Testing is a very process specific chapter, so make sure you practice and internalise the process, and it’s easy marks!

What you take home:

Take-Away solutions for both of our Additional Lessons are linked here, together with the Chat Challenge solutions:




Special Mention:

This week, we will carry on with the rest of our pure math revision, starting with Complex Numbers. Prepare your secrets enclose, warm up a bit and let’s have a fast, fruitful session!

[J2 Chemistry PMCians] Reviewing Equilibrium!


What we did in 2 hours:

This week, we revised Acid-Base Equilibrium, In this revision lesson, we investigated the significance of acid/base equilibrium constants, and used them for pH calculations involving strong, weak reagents, salt and buffer solutions. Explanations of the mechanisms behind buffer solutions are discussed. All the knowledge culminated in the sketching of the titration curve.

What you take home:

Solutions to selected structured questions and homework are found here:
