once I have lifted hood over I find holding the hood down on the outside top edge with one hand whilst getting catch in place properly before pushing lever up helps... Then round to other side and doing the same which is easier once first side is in place
Everyone will have different ways of doing it I suppose... Never really had problems.. Been doing it so long now I find it takes seconds to do.. I exactly find undoing harder than doing up.
Hope you find a way that makes it easier for you
