There's really little excuse for not knowing safety first when working in a lab. That aside I'd say keep your head down and get your work done as quickly as possible without giving him any reason to target you further.

Not sure I can help, we don't give presentations just sit there and go where the examiners want to go, answer their questions and defend our methods. What country are you in?

Give an overview of the area of study, where you see a gap in the literature (research questions) how you'll address those with your project and what this will mean for the field - better analysis/quicker results etc

Every thesis has mistakes, the examiners aren't out to fail you if you can show good science and address everything they bring up during the viva. They may have concerns over it but they'll give you an R+R at worst

Ok, wow, take a breath. Note all the mistakes in your copy or have a list ready at the viva. That's your defence of your work, explain anything they ask, accept that there are mistakes and don't stress over it.

If you feel able to continue with your studies through phd then get an industry job before returning to academia or simply stay and work your way to Professor if possible (job availability) good luck!

You are unlikely to completely fail. It could have problems that your are asked to fix before you pass. Has your supervisor not looked it over and were they happy for you to submit it? Good luck

It's great to have free time - put it to use, learn coding, excel, learn a language, take an online course to fill your time at uni. As long as your supervisor is okay with your progress this could improve your CV later.

Describe the techniques you have used in previous research that you'll be using, be enthusiastic about the project, how it aligns with your career goals etc. And act impressed with the research/facility. Good luck!

Second phds do not help you find a job, they are looked on as proof that the researcher doesn't have real work experience. Unless you're an academic you should look for a postdoc instead, and be published.

Postdocs are universal if you have the right background you'll be hired. Funding issues might restrict some positions but not just because your phd wasn't obtained in the country offering the postdoc.

Hi Caro, does your uni have a stats department you can lean on? I know at my uni you did a sort of freshers course but then had the option of using them for experimental design and analysis? You could ask.

Given the climate right now I'd only do a masters or phd if there was already funding in place, right now imo you don't want to be self-funded.

It comes down to willpower, determination and choice. You can do it, it may take all your free time, even pulling long nighters but if you want to you'll do it. Some people thrive under pressure others wilt. Good luck!

For both my undergrad and master it was about the course, for my PhD it was down to job prospects and adding new skill sets. Also 4 years over 3 meant extra security of income. Whatever you choose good luck!
