Would you like me to quiz you on a specific practical now, or perhaps go over the 'calculations' for cell counting one more time?

It looks like you've sent the same document again. The last part of the document asks:

"Would you like me to quiz you on a specific practical now, or perhaps go over the 'calculations' for cell counting one more time?"

Let me know if you'd like to be quizzed or review cell counting calculations!
