Congratulations on passing your English exam! No matter what your mark is remember that marks are subjective and relative. It is much more important to see your own achievements and use the new opportunities to your advantage.
I hope that your summer will be full of new experiences and emotions. But take some time to work on your English! It should be fun, not a drag. Here are some suggestions.
1. Read a book in English (preferably download the audiobook as well). You will improve the language and have fun. There are plenty of free downloadable resources on the Internet. Try to check out http://englishtips.org/, http://manybooks.net/, http://www.gutenberg.org/ or find something else.
2. Do a free online course on the subject you are interested in: https://www.futurelearn.com/.
3. Work on your pronunciation: http://www.bbc.co.uk/worldservice/learningenglish/grammar/pron/.
4. You could also improve your listening comprehension with the help of this nice site which offers you to complete song lyrics: http://lyricstraining.com/.
5. Browse some interesting materials from http://learnenglish.britishcouncil.org/en/, http://www.bbc.co.uk/learningenglish/ or any other educational websites. Catch up with your grammar using their materials and tests.
6. Watch films.
7. Try to speak English. Use any opportunity that presents: give directions to the foreigners, communicate in English on the holiday abroad, find friends in Skype or facebook.
Your future progress depends on you, not your teachers. Be active and motivated.
