Hi Carolina
There are number of things you can do during that time.
- If you are interested, there are always some nice "summer school"s, in different countries, e.g Germany, ... Some of them even might have scholarship, so no worries about costs and ...
- If you wanna find a job in the UK, the best way is going through the websites of companies and see what they offer. In the UK, most of the large companies have schemes to get students, but normally for a longer period of time than 2 months (maybe 6 months or a year). But still there can be opportunities to gain short term too.
I would suggest, to get a list of companies, have a look on their websites, and get in touch with them. Email them and then call them, and see what they have. I am sure you will find something. You should start this process soon, as it takes normally some time to arrange everything.
Also it is good (even better) if you could get in touch with some people within companies, those who can arrange things more easily and faster.
Arranging such working time, will be very good, in one hand gives you some experience, good for your CV, helpful for future job hunting, and more importantly, it brings you some connections to some professionals, which will be definitely helpful in future.
Hope this would be of help. Feel free to ask if there is something unclear.
