HI Naasha,
Congrats for the completion of CS Executive programme!!
Make a note that marks are just required to get the certificate and you get the marks on how you performed your examinations,right?
Don't be so scared that because of low marks your career opportunities will be decreased if you have enough knowledge on the subject than i am sure that you will certainly get a good exposure in the market in which you want.
So for that always make yourself updated and also and make yourself fully conversed with knowledge in which you want to start up your career
All the best!!!!!
Regards,
Ranjeet
