Success of my friend

Today I heard a the good news that one of my friends has been admitted to a famous university. I am very proud of her. but Many people doubted her when she told us her decision to apply for the University because it is very difficult to through pass the entrance exam of postgraduate in that university. Now she has proven to us that she did can do it. In Over the past few months, she has worked hard and tried her best to prepare for the exam. She told taught me a lesson that it is possible to achieve our dreams if we work hard and believe in ourselves.

Congratulations to your friend. Remember to always put a space after a full stop before starting the new sentence.
