[S4 Physics PMCians]

What we did in 2 hours:

On 19 and 20 Sept, the S4 PH has come together to complete the following:

1) The Final Lap – COE & DC Part 3

What you take home:

In this coming week (Sep 26 and 27 Sept), we will continue our revision through with Magnetism and Electromagnetis.

Do remember to always bring your Secret Enclosed AND the revision books for all lessons.

Do bring along your calculator for the lesson.

Special Mention:

We are moving on to Set E and Set F next week, focusing mainly on Trigonometry. Do remember to bring your Secret Enclosed too. See you either in zoom or onsite!

[S4 Chemistry PMCians]

What we did in 2 hours:

We have completed our revision on Atmosphere & Ammonia as our final topical revision. We used our knowledge of stoichiometry to make sense of the percentage yield of ammonia (normal stoichiometry assumes 100 % yield – theoretical yield!).

What you take home:

You should begin attempting the take home questions on Ammonia and bring questions to clarify in class, if any.

Special Mention:

Please also find attached for the solution to Question 15 (Extraction of Metals & Rusting) of our Metals EOY Revision Notes, as requested by a number of you.
