ISCA is a core subject in all the CA, CPA, CMA courses abroad.
The developed countries are way ahead in the field of ISCA.
This is a hot field. If CA's will leave this field. CMA and other finance courses will take advantage.
Its a theory subject but its you who can make it practical. If you have knowledge about practical issues you will be valuable for any employer.
We have to look beyond books. Use of Internet is invaluable.
How many of CA students know about KIMDOTCOM, The case of Edward Snowden, Julian Assange, The revelations of Wikileaks, The latest cyber war between USA and North Korea over the movie " The Interview", The closure of Piratebay, The NSA revelations.
To understand these events, knowledge of Boring ISCA is of utmost importance.
If you can flaunt knowledge about these events, your competitive advantage will go up.
This is how IIM grads prepare. And we CA students are still thinking what is the use of ISCA.
