MOST IMPORTANT PREDICTION EVER: Those who study will be rewarded.
Following the trend, however, I think it will be easy. If anyone sat for Chemistry and Biology, you might know how big a joke Chemistry P2 was (an insult to Chemistry itself) and Biology P2 was also easy, if not very easy. Conversely, Biology P1 and Physics P1 were tricky to the least. Hence Physics P2 should be easy. However--be warned, Chemistry P1 is probably going to stand up for the subject so prepare well for it.
