I'm also 52. The whole paper sounds like laboratory and investigation technique, both of which I do not possess.

Any tips?

I am confident enough for planning.

 Still finding ways for analysis. Like Describe the graph/results etc.

For stats just UNDERSTAND and thats it. I memorize some of the definitions and questions of past papers.

For stats they always repeat.

ANYONE knows how to analyze data?? Like which one is anomaly, why, desribe blah blah blahhh

A solution of substance Y, thought to be a growth hormone, was made by dissolving a known
mass of Y in 10 cm3 of distilled water. This solution was added to samples from a culture of
animal cells containing 3000 cells per mm3.

Guys, Check out the EXAMINER REPORT

MUCH MORE HELPFUL THAN THE MARKING SCHEME

 YOU GET TO KNOW WHAT WORDS THE EXAMINER WANTS YOU TO USE

THEY EMPHASIZED SIGNIFICANCE, RELIABILITY, ACCURACY AND PRECISION

THEY ALSO TELL US THE COMMON MISTAKES SO WE CAN AVOID THEM

Those are my inputs for 2mrw's papers

Good luck guys :D :D :D

Read the questions properly bro

3000 per mm^3

The table refers to THOUSANDS

so 3000= 3 thousands= 3
