Having a degree is always worth something. You never know how life plays out, we all never expected this pandemic to happen and it did. Lets say for whatever reason dental school didn't work out, or you had to unexpectedly move and you can't finish your degree. At least completing a degree you know that you have a bachelors and you can find a job after if things don't work out. You may have a plan but clearly from this year's experience plans can go out the window in a drop of a hat. I say for sure finish your degree and go from there. There's a reason why almost everyone finished their undergrad, because if all else fails thats the thing we can all fall back on. Otherwise, if you don't complete it, the only thing you will have is a high school degree, and there isn't much you can do with that. Have more confidence in yourself and also challenge yourself. you kept up your grades this far, what would prevent you from doing well in your fourth year? Often times we make decision in fear and end up regretting them. Most people on this forrum are urging you to finish your degree for a reason, we all know that this is the one thing you can fall back on. Not completing it is a big mistake in my opinion. You can always say that you can go back to it in the future, but statistically thats very unlikely. Again, you don't know what life would be like then, maybe you have kids or a family, or maybe you moved to a different country, etc etc.
