Dear Sir,
I am pursuing 
in 
the course name "The Concept of design thinking" in the morning batch starting from 10:00 am to 12:00 p.m. I am writing Change preposition
apply
this
 letter to inform you about the situation in which I am not able to continue my class. 
I am working as a Senior Designer in multinational company. Lately a training has been introduced in our office, which is mandated for designer to attend. The main problem is  that the training is organised in Delhi for a month. Linking Words
Therefore
 I am not able to attend the Linking Words
further
 session in person.
It would be great if you provide study materials, online tutorials and popular website for the same, which I can study during interval. Linking Words
This
 would be helpful for me to  stay connected with the things I have studied so far. I will resume my classes once I back.
Thank You in advance. I hope you understand the situation. I would like to hear from you as soon as possible. 
Yours faithfully,
PreetiLinking Words
