Company Secretary

CS is a very lucrative professional carrier
Even if student has passed Executive level and has studied and appeared for final then also he/she can get a job but the student should've taken 15months/1yr/2yr/3yr training then the chances are good to get a decent job

you get exemption from foundation programme.

it is up to you and also how strong your fundamental skills are . I personally think, 11th is a bit early to start coaching. the syllabus for the foundation level in CS is manageable without coaching provided that you have a good commerce background. just look at the syllabus and decide for yourself.

There are 3 levels foundation executive and professional
After Bcom you can join executive level

Company secretary is a lucrative career option and can be completed in 3 years
Therefore you could be CS before graduation and the opportunities are plenty
IAS is difficult than CS and might take longer

As stated by the institute itself, here are all the opportunities

CS scope has increased since the passing of companies act 2013
Earlier CA used to earn more now it has reversed
The appointment of CS is compulsory for companies having capital more than 5 crore
The compliance field is hot now and only CS can give services in compliance
CS can also be appointed as internal auditor
There are other opportunities as well eg due diligence in securities
Even CA is good
Chance of passing CS is greater than CA
Cs comprises of law related subjects like company law , securities laws
CA is more of accounting taxation and others
So overall go for CS if you have liking towards law
