Congratulations! I do hope you enjoy it.
I had blogged about my university experience when I was at queen mary, do check it out:
https://thenextchemist.wordpress.com/Like with most degrees from any university, you won't be able to find a job if you don't put in the hardwork yourself.
Students can go a whole three or four years at university without joining any societies, taking part in any extracurricular activities or applying for any internships and then complain about not being able to get a job after graduating or perhaps, blaming the university for not placing you a pathway to success.
Queen Mary offer so much support and opportunties for students to network.
I highly recommend joining QConsult, Qtemps, volunteering scheme or other programmes queen mary offer.
http://www.careers.qmul.ac.uk/jobs-and-experience/The careers centre is also very helpful and have won awards for providing students with job support, you can sign up for weekly updates for networking opportunities as well as internships.
Queen Mary also offer summer or year abroad schemes which many students take on. Some of my friends have been to china, malaysia, america, austrailia, etc.
As a biochemist, you will also be in the labs - you can ask your favourite lecturer or your advisor if you can do an internship with them over the summer during your time.
And there's also the obvious option of looking online for work placements, year in industries and internships during your 3 years at Queen Mary.
So as you can see, the opportunities are endless but it's all down to you at the end of the day
I hope this helps and good luck!
