Erratum on my bachelor Thesis I have written a thesis for my bachelor degree and next week I have to defend it. The problem is that I found some small mistakes (not spelling mistakes, but small mistakes in equations, a wrong number in the abstract and so on) and one or two more significant problems. 
Now I want to write an erratum on my thesis that handles six different of these mistakes. Is this too much? I don't want the jury to think that I was sloppy with writing the thesis or that I didn't check it before I handed it in (I did check it numerous of times).

So, is it normal that an erratum contains so much mistakes?
A thesis is generally a pretty big document, and it would not be surprising to have a number of mistakes even after several passes of editing.  If I were on your committee, I would be happy to see you submit such an erratum, because it would indicate that you are continuing to engage with the material and actually concerned about its quality, not just trying to graduate and leave.
