Submitted my thesis couple days back. When preparing slides for the defense, realized i made a calculation mistake in 2 out of the 4 chapters in the concentration of drug used. The results are not affected, just that i expressed the wrong concentration (quite a few; 0.6 instead of 0.3... things like that ) it has happened in 2 chapters.... My defense is next thursday followed by the viva..... i am freaking out if it is going affect my passing the PhD any difficult. I know that is the only mistake.... please advice guys....
