Hi. My corrections in bold! My notes in Italics!

English in 30 days

Today I got up with a firm decision to change my life radically during 30 days. I set a target to learn English during this time to apply for a job (apply for a job or apply for jobs). Everyday I am going to write reports about my study. I will learn by heart new words ('learn new words by heart'; 'memorise new words', 'expand my vocabulary'. Your expression 'learn by heart new words' is charming but a little old fashioned . . . alas), make sentences and write essays. I understand if I do not start today, then will be late. I will put in order my thoughts and actions ('I will put my thoughts and actions in order' is more usual but see my previous note). I count on your support, my friends!
Today`s program:
1. Grammar: Prepositions and their use.
2. Essay: My town (work on description)
4. Speaking: Preparation to the interview with volunteer ( Make questions)
5. Make 30 sentences with new words.
Let`s get started!

Good luck!
