Modern/contemporary Physics

Hello guys (:

I’m preparing for the SAT Subject Test in Physics I’m going to take in October. I have PR for Physics and because I’ve learned modern physics only from prep book I feel like I’m not comfortable with come concepts, especially radioactivity/special relativity so I’m searching for something I could get more practise with. Any suggestions?

Question #2 . In PR there is a section called “contemporary physics” that tells a little about theories and history of modern physics but I’m not sure if this is enough. I’m aiming for 800 so I want to be sure I know everything and I won’t be surprised when the day comes. What is your experience?

Thank you in advance (: !
