I passed EIKEN Grade 1

I think IDIY is the best choice for busy businesspeople to study English writing. I had no confidence in expressing my thoughts and opinions in English before starting this service. However, practicing with the teachers of IDIY made it possible for me to communicate in English. Thanks to the great teachers, I passed EIKEN Grade 1.

I passed the first Medical Interpreting Skills Exam

I started to study English writing skills on IDIY and IDIY-biz. At first, I couldn’t understand what I wrote in English, but my teacher taught me useful expressions with kindness and tenderness. I passed the first Medical Interpreting Skills Exam (descriptive test) in 7 months.

I obtained the English Tour Guide certification

I obtained the English Tour Guide certification, a national examination, where applicants have to take examinations in English, Japanese history, geography and general knowledge.

My TOEFL score increased from 43 to 52

I started IDIY 2 month ago. I did not have enough skills to write essays and reports. After I took some lessons, my TOEFL score increased from 43 to 52.

catymcd (Instructor)From England
I enjoy the challenge their importance offers and am extremely motivated to correct each order to the highest standard. It is very important to me that all the orders are edited to sound as natural in English as possible.I understand how important accuracy is to the customer and how an edited piece of work will reflect on the customer. Therefore I always aim to correct a piece to sound as professional and natural as is possible. I am a native English speaker so you can be assured of the accuracy of my editing.I look forward to working with you.
Kris W (Instructor)From America
I do more than just correct grammar and spelling. First, I read through your composition to ensure that I fully understand the deeper meaning. Then I make carefully selected changes to ensure that each sentence sounds clear, professional, and persuasive. I always respect your efforts and strive to maintain your unique voice. I help you express your thoughts in a beautiful and natural way.
Ellie P (Instructor)From Canada
I am a writer myself, and have been writing articles for many years and am now working on my second book. I take every piece of writing very seriously and try to do my best to understand what is not being said as well as what is being said, if it is a subjective piece. First, I try to retain as much as possible from my customer’s writing. Then, my second sentence is more liberal. This way, the customer has two suggestions. Sometimes though, one is all I use. I consider it sufficient.
