You'll see 118 H&E tiles, one at a time. For each, say whether you think it is real tissue or computer-generated, and how sure you are. Roughly 20 minutes in total.
Use the full scale — "probably" is a real answer, not a hedge, and is more informative than a confident call you do not feel.
All tiles have been stain-normalised to the same reference, so colour and brightness carry no information about origin. Judge on structure.
A comment box is there if you want to note what drove a call. It is optional.
