For people who don’t know,
Marks really doesn’t matter much when you apply fot PhD, it’s majorly why you want to do a PhD and any experience in terms of any sort of research you conducted during UG/PG/Job experience.
A student just after his/her bachelor’s can also apply for a PhD. Masters isn’t a compulsion for getting accepted for PhD.
To apply for a PhD, you need the following documents,
Eligibility for PhD in general for UK is,
As most of you will already be in UK doing a program, one simple way is staying in touch with professors who will be teaching you and accept PhD students as well. You can work under them during your bachelors or masters program as an assistant to gain some research experience which will later help you get a PhD.
Second way is check out available positions in different universities. You can visit findaphd.com or jobs.ac.uk/phd. These two websites advertise open PhD positions throughout UK along with funding status, last date, etc. If you find a PhD suitable to you, I would suggest you to drop an enquiry mail to the professor in the advertised position showing your interest in that position and discuss the idea before submitting your application. This increases chances of you getting accepted.
Another way is if you have your own idea, you prepare a proposal and start dropping enquiry mails to different professors working in that area in different universities asking if they are accepting PhD students.
There is another PhD called a 4-yr CDT PhD, which basically has 1 yr of coursework and then 3 yrs of research. These PhDs are funded by EPSRC (UK Research Council) and are 95% reserved for UK students only but are always worth a try.
Now talking about funding, a PhD can either be fully funded, partially funded or self funded.
Most of the PhDs are partially funded, very few fully funded for international students and self funded PhDs are easy to get but isn’t much valuable, because professors happily accept self funded PhD since you are going to pay for everything and they have to do nothing for you.
Fully funded PhD means you get your tuition fee waived off and a stipend of almost £1200 per month.
Partially funded generally is your tuition fee is waived off. No stipend.
Self-funded is you will pay tuition fee for 3 yrs and obviously no stipend.
Apart from already funded projects, there are outside orgnaisations and charities as well that fund research within PhD.
One of the most common one is Commonwealth Scholarship and Tata Trust. You can google about charities and organisations funding PhD to find out more about them. These fundings and scholarships are generally for people coming with new ideas and a new research proposal and extremely competitive, not at all easy to get.
