Have done 2010, 2009 and 2008 in this sequence found 2008 is the hardest. Did not have time to finish all and unfortunately omitted couple subquestins, usually after filling a template.
Thought it was pretty rough myself.
I thought 2007 was the hardest of all.
2007 is hardest for me
2007 for me too. Got a paltry 67%
It was 2008 for me. 2007 was bipolar, tons of easy parts and tons of not so easy.
I didn’t do 2007, but 2008 was pretty rough. I felt 2009 and 2010 were decent though.
