CLEAR YOUR CHEMISTRY ADVANCED PLACEMENT WITH EASE!
Clausius Inequality, Helmholtz Free Energy, Steady State Approximation and many more. Are you having difficulty grappling with these topics?
At Focus Chemistry, we will enlighten you with the definition, derivation and application of all these concepts, which will be tested during the placement tests. The recommended duration required for the preparation of these placement tests (CM1121 and CM1131) is at least 4-5 months.
We offer the following:
- Notes used in both local and overseas universities such as NUS, NTU and University of Sydney.
- Tutorials and Assignments coupled with solutions from the universities.
- Linking concepts learnt at A Levels / IB / Polytechnic, which are necessary to excel in the placement tests.
