I am in the UK and I completed an undergraduate dissertation. In my dissertation I went much higher than my level. All the content in my dissertation was at a masters level and everything was self-taught. However I sort of came undone in my viva, where I was told I kept jumping into stuff.
I was wondering, when writing an undergraduate of a masters dissertation, is it better to go above and beyond your level and be ambitious or make sure the document is written very well and stay at the level you are currently at?
