Hello everybody!

I am going to take the IELTS Academic and I would like to practice my writing skills. Can anybody suggest some useful phrases that can be used? like As it can be seen from the graph, on the other hand, etc. other useful phrases to compare or contrast or words to avoid the use of I, WE would be highly appreciated

Hello everyone! My name is Francisco (but you can call me Francis or Frank) and I'm from Venezuela. I'm a Spanish native speaker and I want to improve my English Skills. I did a research on Google because I would like to find a partner who desires to help me with my main goal: become a fluent English Speaker. 

Hello, I'm here to improve my English and meet people who speak this language to help me in this purpose

I updated my profille today, and wrote it below. Could you correct or change them to natural phrases? Thanks!

It's one of the most important success in the box-office history

Dear Professor,
