Unless the questions were meant to deceive you and trick you I thought this was really easy...
Until the first writing bit where it suddenly just got so much more harder. The solar panel question was hell
All I got was economic benefit for the first one and the there was sunshine for the last one
got no disadvantages....
Last question weirdly was the easiest... "Physical exercise" is what I believe they said so that was shockingly easy.
Overall - the paper was of a hard medium difficulty
To sort this out...
USA had good
Brazil + uk had mixed
Australia had bad.....
I learnt what a refuse collector was
The question about the house party was jokes with the police cone in and the lipstick on walls. Thought exams were meant to be serious
I failed to get 2 of the 8 marks on that but I'm quite sure I got the other parts right.
The last question was hard. I got all advantages if smart phones etc but none for TV and radio
Overall - difficulty was easy medium for me
