# [J1] Term 1 Week 7 (17-23 Feb) Updates/ Debrief

[J1 Physics PMCians] Starting off well!

What we did in 2 hours:

We again reinforced your understanding and ability to tackle calculations on Uncertainties (Errors). Then we started on reviewing Vectors, and how to calculate the components of vectors and use this concept to calculate the resultant vector.

Special Mention:

You would have received the Daily Dose for Measurements and Uncertainty, which is our specially crafted compilation of exam questions, with working and answers at the back. Please attempt these questions to ace this topic!!

[J1 Maths PMCians] Inequalities & SLE

What we did in 2 hours:

Having wrapped up Inequalities with some challenging questions, we took on the friendliest chapter of the syllabus, System of Linear Equations.

What you take home:

These chapters are foundational chapters of the syllabus and are commonly integrated into other higher-level topics. With a firm foundation here, this gives you the confidence to manage them in future! Do practice your Daily Dose questions and check back with your tutors!

Special Mention:

This week we move on with graphing, starting with a maybe familiar friend, conics.

RI Class: RI students are reminded that the Wed 5.15 class at Bishan will be doing Functions. This is not an easy chapter to pick up, so be ready!

[J1 Chemistry PMCians] Calculations Galore!

What we did in 2 hours:

We have completed the chapter on Atoms, Molecules and Stoichiometry and have moved onto Redox Reactions. Let us recall what kinds of concepts we have covered:

1. Calculations for Back Titration
2. Calculations for Combustion of Hydrocarbons
3. Revision on Redox Definitions

What you take home:

You should have received materials that will aid you when you wish to revise the chapter on Atoms, Molecules & Stoichiometry. They are:

1. Take Home Questions – These are specially curated questions that serve to remind you of key concepts, methods and ideas on the chapters. Solutions are provided at the back of the booklet for your reference. If you need additional help, do approach me before or after class.
2. “Everything you need to know” – This concise summary sheet helps you to recall and consolidate all knowledge and methods you need to know for that particular chapter. Write it in pencil so that you can erase and try it out another time.

The solutions are found here:

Special Mention:

How did the new units of mol to calculate amount of substance come about? Look at the video below to find out more.

This week, we will continue with Redox Reactions and deal with A Level style calculation. Remember to bring back the booklet you received last week!
