# [J1] Term 1 Week 6 (10-16 Feb) Updates/ Debrief

[J1 Physics PMCians] Starting off well!

What we did in 2 hours:

We started our 1st lesson with a review of Units & Measurements. But we went on to explore the concept of Uncertainty (also called Error), looked at the shortcuts to calculate it & emphasised how you can always determine the error using our “Traditional Method”.

Special Mention:

In the next lesson, we will continue to reinforce what you have learnt, by letting you attempt exam type questions.

[J1 Maths PMCians] Applications of Integration

What we did in 2 hours:

Welcome to your J1 H2 Math course at PMC! This week we began our introduction to H2 Math with Inequalities, which should be a very accessible chapter. Do touch up on your GC skills when you have time!

What you take home:

Some additional practice for your Inequalities is provided with the Daily Dose. While the lesson will have prepared you for the concepts involved, some are still on the challenging side. We will be trying out some of the more challenging questions in this week’s lesson!

Special Mention:

This week we will clear the last few Higher Order inequalities questions and move on to System of Linear Equations. Do remember to bring your GCs!

[J1 Chemistry PMCians] Get ready for calculations!

What we did in 2 hours:

A very warm welcome (back) to all of you!

We have just started the H2 Chemistry syllabus on Atoms, Molecules and Stoichiometry, which is definitely something you will need throughout your 2 years. More specifically, we discussed concepts such as

1. Relative Masses
2. Calculating relative atomic masses
3. Four formulas to calculate mole
4. Finding empirical & molecular formulas
5. Limiting & excess reagents
6. Percentage Purity & Yield

What you take home:

You should have received a Data Booklet as well. Please remember to bring it for every lesson!

Special Mention:

This week, we will continue to look at harder calculations involving back titrations and combustion. Please remember to bring back the booklet that you have received this week!
