When you go for college some of the common advice are:

• Don't neglect your curriculum. There can be seniors telling you that studying a week before exam will be sufficient but don't go for that. Study regularly and remember that without knowing the subject entirely you will not get a job.
• Don't think that college curriculum is sufficient. In order to get job not only the college curriculum will help you but you have to make some efforts by yourself in order to learn some industrial skills which will give you a better opportunity towards job.
• Discrete Mathematics is the key to any branch of Computer Science. So learn it as much as you can.
• Learn programming languages solely and responsibly.

This are some of the points I would like to point out in order to have a good career.

I hope my answer helps. All the very best for your future endeavors!
