Letters / No longer attend regular English class [4]

Dear Mam,

I had joined your general English course to improve my English , to achieve maximum band in IELTS. These course help a lot to speak fluently since two week, but as you know that I was searching Job in my field. I have to Join on Job to earn some money coz my family financial condition is not good with learned general English as well. due to these circumstances I decide to learn English with my own to avoid clashes of timing between my job and tuition. That's why I inform you with regret that I have no longer attend your general English class from next week. Though this decision surely wrong from one point of view but I have to do for betterment of my family condition. My responsibilities are much more than my future towards my family. I can also learn English my self of course with much more effort but its shall be manageable in this condition. Hope you understand my situation and allow me to leave from your course in between. I am always thankful to you for your efforts.

Thanks & Regards,
Denis.
