I'm planning to join a 1 yr diploma just for boosting CRS score .. any easy diploma recommendations will be appreciated…

You can also find pg diploma related to computer science as well. But, if your focus is just to increase CRS then can simply go for pg diploma in business administration as well.

Annamalai is best where fees are quite less however the transcript fees are 5700 but still it's better

PG diploma from IGNOU. Cheap and evaluated by WES as well
