Hey, since this is an assignment I can't be too specific with suggestions for improvement but there's a few things to be aware of:
- check your hypothesis
- very informal and casual language doesn't belong in your report, you also have some spelling mistakes (e.g. where vs were)
- abstract and introduction aren't the same thing - make sure you know the roles of each
- check your diagram gives all of the information it needs to (atm it doesn't)
- some of your sentence structures don't follow convention (i.e check your grammar & punctuation use)
- being a measure of retention and being "good for retaining" are different things
- be careful with scientific language conventions
- the discussion should be the longest part of your report (note: this shouldn't be from fluff, it should be from analysis, interpretation etc.)
- Why are results and method grouped together?
- make sure you provide full references at the end
