is it just me or was it easier than chem and bio?
It was certainly easier than chemistry, but the biology one...well, that's certainly subjective!

would you get a mark if you put for maximum diffraction the size of the gap has to be about the same size or almost the same size?
The smaller the gap the larger the diffraction

They should be equal. If the gap is smaller than the wavelength, the wave cannot pass through the gap. That's why your microwave oven uses small holes for trapping the microwave but not a full metal plate

For maximum diffraction the gap has to be equal to the wavelength
