Swaps and Collars!

Hello Sir,
Firstly, i would like to thank you for providing students with great lectures… After watching your lectures on Foreign currency risk management and Interest rate risk management, i feel comfortable with with these areas..

I could’nt find any lectures on Swaps & Collars.. Swaps and Collars have been examined frequently.. So where should i prepare from? I am almost done with P4, my only weakness was Risk management.. could you please guide me on where should i read & practice regarding Swaps and Collars?
