You probably missed out on some of the exiting algorithms that all CS students learn, but don't worry I think few knows them without looking them up years later

You probably missed out on some of the exiting algorithms that all CS students learn, but don't worry I think few knows them without looking them up years later. It is hard to know what you have missed, since you specificly say webdev, you can get by with very little knowledge and still make functional websites. Im guessing that low level stuff is what you are probably missing, maybe some design patterns. I think the best way to get validation of your skills is to get your work peer reviewed, either by working in a shop that actually does code reviews or participating in open source or even just putting your own stuff on github.
