Company Secretary

As you are thinking about CS with interior decoration, so you may be interested in computer related designing. Combining both, you can go for web designing or architecture. If you are not interested in the two options mentioned above then pursue B.Tech as interior decoration is no big deal if you have a good knowledge of decoration after completing B.Tech, you can learn interior decoration. Please do a certificate or Diploma from a good institute. It all depends on your interest, finance and artistic talent.
Best of luck.

Dear Udit,
Yes, one can pursue regular college alongside professional course but before to that, check for permission from the ICSI. Secondly, my recommendation is to go for regular college only if you are getting admission among one of the best colleges. Else, opt for correspondence graduation and concentrate on CS.
All the very best.

Going for MBA will be good since if you get appointed in a company as a director then management degree will help you there, but ultimately see what you are comfortable with doing.

There are a good number of jobs like finance analysts or research as they are highly competitive.

CS is good and provides lucrative job than MBA since Companies Act 2013 has opened up a lot of opportunities for CS professional. However, do CS only if you are really bright and very hard working student. MBA is also helpful if you do it from a good institute.

Doing three of them together is quite difficult and unnecessary. Instead, combination of any the above two like CA + CS or CS + LLB is recommended. Most people prefer CS + LLB as it gives full scope in company civil and criminal law.

CS is conducted by only ICSI institute in India.

Hi Kriti,
It will be difficult for you to seek admissions without mathematics. You should first check with the colleges. For computer sciences countries like US, Canada, Germany, Singapore, UK, etc. are very popular. Kindly, write to the colleges firstly for eligibility. You may refer to ranking tables like Times Higher Education for popular colleges globally.

You can pursue CS after completing class 12th. You need to qualify CS foundation exam. If you are a graduate then you don't need to take the CS foundation exam.

CS has a better scope as compared to CMA. The companies act has opened many new job opportunities for company secretaries. CMA is good too but not as good as CS.
