Believe me I had similar thoughts. I thought Capstone Project was going to be extremely tough to execute. But believe me it isn’t that tough if you choose a good mentor and an area of your interest. If you still feel it’s going to be a tough nut to crack, you can apply for internships in reputed companies of your domain.
Try to develop a mentality of learning something from the project rather than getting scared of it.
VIT doesn’t fail anyone in Capstone Project. If the external reviewer feels your work isn’t good enough, you are given few more days to add some more value to it.
