I have been attempting this crossword for some years.
At the age of 79 with what I think is reasonable general knowledge I would complete about 50% of it each week.
Acquiring a computer increased this to about 90%.
Sometimes son was able to help. Always two or three clues not apparent on Google.
Answerbank since last month supplies missing answers,
usually within minutes.
I consider this crossword difficult, every week at least one
word I have never seen before, yesterday's example
malacostraca.
I agree that many people cannot check previous answers before posting their question.
