# [J1] Lesson 39 (Mechanics Year End Revision Part 3 – Mock Paper+ Differentiation 2+ Chemical Kinetics 2)

[J1 Physics PMCians] Mock Promo Paper 2

What we did in 2 hours:

This week, we conducted a timed trial test for Paper 2.
We are confident the review was valuable, not only to reinforce the problem solving techniques but to hone your exam skills.

What you take home:

Special Mention:

Gentle reminder that there will be NO J1PH classes for the next 2 weeks, as you will be in the midst of your Promotional exams.
We wish you the best of success in all your promo papers. Looking forward to the good news of your results!
Cheering you on!!

What we did in 2 hours:

Wrapping up our revision was the last part of Differentiation. Having gone through a wide variety of questions, do review and recall the tips and tricks we practiced to make the questions go more smoothly!
On top of applying your skills involving Tangents & Normals, Maxima & Minima and Connected Rates of Change, always remember that managing Parametric Equations (have you considered the domain of t?) and doing things like squaring both sides to make differentiation easier, and clearly identifying the constants and variables in the question, can make the difference between struggling for 30 mins and breezing through the question.

What you take home:

As per our announcement of Sunday, all solutions have been uploaded, do review whatever you need!

This is the week, let’s put on a good show!!
All the best!

[J1 Chemistry PMCians]

What we did in 2 hours:

We have concluded one of the more perplexing chapters in Physical Chemistry – Kinetics. This is a chapter that uses a lot of math, and being foundationally strong in math certainly helps. We looked at how we can use experimental data (via tables and graphs) to find the order of reaction, and see how the rate equation relates to its mechanism and energy profile diagram. We then discussed the impact of catalyst on the reaction rate.

What you take home:

The solutions to the incomplete Kinetics questions are found here:

ALL THE BEST FOR PROMOS
We will take a 2 week short break from 28 Sept to 11 Oct. I will see you for the Headstart programme on the week of 12 Oct.
Take care and good luck!
