Distance/Correspondence

Hello,
Actually, it is you who is going to decide whether it is worthy or not. If you have done a course related to it through regular mode then you may take a chance to go for the correspondence mode.
However, my suggestions are:
1. If you have any full proof plan then you may go for that. If you think that you can do well in voice culture without going to any coaching center or institute then yes, you may do so.
2. Only think about distance learning in professional voice culture, if you are doing any relevant job simultaneously. It will give you practical job experience in parallel to your studies.
Hence, now you are may be getting the point to whether go for distance learning or not.
I hope you are getting the point.

Screenwriting is related to film and TV where creativity and newness is the key to making your work known and successful. Where do we see distance learning as the foundation of such an exposure and development of creativity that we recommend a course through distance? I do not recommend a course of this type and kind and stature from any institution of the world through distance.
It is advised to dare to do this course from distance if only some platform to learn the same way and under expert supervision is already available or the person has been learning/has learnt the screenwriting, creative writing and now want to give it a certification so as to get some job which needs such a certificate as eligibility.
Distance mode has its own limitations and that's why we do not recommend that. Besides, Indian Distance Education has not reached that level of perfection where such courses can be made worth doing.
