# [J2] Lesson 25 (COE+DC Final Revision + Integration June Revision + Organic Chemistry)

[J2 Physics PMCians]Aceing Circuits – all you needed to know!

What we did in 2 hours:

We took time to reinforce our problem solving skills for Current of Electricity & DC Circuits. We are confident after the 2 hours, your problem solving techniques have improved to ace this topic!

What you take home:

COE & DC (Round 2) Solutions:

Special Mention:

Next week, we will review the concepts in Electromagnetism (EM). Come and find out how much you’ve improved and understood. 🙂

Till then, enjoy the increased freedom in Phase 2, and look forward to seeing all of you again!!

What we did in 2 hours:

Moving on to Integration for our Calculus revision, we recap the techniques and apply them to various styles, on top of applications onto areas and volumes. Do note the particular types covered in Secrets Enclosed, including the examples on factor formula, as this has been widely used in recent years’ exams.

We covered a variety of applications, including regions between two graphs, modulus graphs and engineering application. Do note the way the periodic sine and cosine functions are evaluated, as this has been done in recent A-levels papers!

What you take home:

Worked solutions for Q5&6, as well as for the Calculus Take-Away Questions, are linked here:

Special Mention:

In this week, wrapping up our Calculus revision, we will be covering Differential Equations.

What we did in 2 hours:

We have finished looking at the reagents, conditions, reaction types and key features of all the reactions of carbonyl compounds all the way to nitrogen compounds. We moved on to consolidate all these information through Organic Synthesis, requiring you to convert one functional group to other, often with multiple steps in between.

Special Mention:

We will continue our revision on Organic Synthesis next week!

See you (online)!
