Personally, many of the questions are achieveable, the only difficulty is organic- Attempting to see where to start; usually working from the end product to the start works; from here you can see where to progress between intermediates. I particulary enjoy the inorganic, analytical and mathematical element of the olympaids, they enable one to think and explore the concept even further by combining elements of specific sections together. Last year's paper was nice, hopefully this year it is not as bad!
Good luck to everyone sitting their exam, remember any award is very respectable. I am aiming for Gold
