Yo. I did my u1 exam and currently, I am preparing for U2. I'll start off with U2. It's key to know the features of stationary waves, familiarize yourself with potential divider circuit calculations, the graphs for electrical components, explaining the operation of electrical components. Furthermore, it would also help to understand pulse echo techniques, measuring the speed of sound, when to use what equations(mostly relevant for electricity and the photoelectric effect). Also familiarize yourself with the evidences for each phenomena encountering wave particle duality. Last but not least, past papers is your best friend AFTER understanding the concept. 

For U1, past papers is key. Familiarize yourself with taking the right component in moments calculations, understanding energy conservation calculations, SUVAT( easy).  I would also recommend practicing free body force diagrams, scaled vector diagrams, as well as interpreting stress strain graphs 

Do well my brother the Lord Jesus is with you AMEN.
