Start learning. Start reading. Start listening.

There are many ways to learn. Books. Videos. Professors. Friends ( So true. )

Find your way. But I would say, try all of them. Since doing the same thing again and again might make you feel fatigue. See videos, and if it starts getting boring, take a break, read something about what that video you just saw and get back to the video. Or just continue with reading if the book pleasures your eyes :D

Ask doubts to your professors if you think commenting on a tutorial video and getting a response will take a lot of time. Or Google your doubts. Be patient and keep searching till you get it.

Or talk to friends and discuss doubts. You could also discuss with friends about what you learned and learn from them and teach them too. Explaining a concept is one of the best ways to learn the concept. So, teach and learn. Don't have a friend to teach ? Write a blog like me :P or take a seminar in your deserted room ;) And it would be cooler to do it in front of a mirror :P Or, better, take a seminar in your class ! That is if you have the guts :P (Yes, I am basically challenging you to take a seminar)

These are some ways to just keep learning and feel good that you are better than what you were yesterday. That's the only thing you should care about. Don't compare yourself with others. I know it's a hard thing. Still. At least try not to do it.

And here's a link to a video playlist that I found in YouTube. Many must have tried it out. The videos look awesome to me. It's "Introduction to Algorithms" by MIT OpenCourseWare.

I love to write about such stuff that I learn. And even make tutorial PDFs. But the actual source is the best any day :) So, I recommend you to watch the above series. At least a few of them. Ones that you feel that you must surely watch.
