That's how I've done it my entire life. I just broke 2000 In tactics a few days ago. It's not a good method, but when the time comes when I can only do tactic after tactic I will do that. And attempt my best.
How to get a Tactics Rating of 2000?

If you're skipping tactic because you cannot find solution and don't want to lose points, then you are literally wasting the amount of time you were attempting solve it and learning nothing.
It really sounds like to me that the people doing that rather have a big rating than having a big tactical vision.
You will improve a lot faster you you get the solution the the problems you can't crack and recognize the type of patterns you miss.
Or maybe I am delusional and what I said is total nonsense?

Statistics will probably show, no will show, that the vast majority of tactics you skip will be of similar theme. Skipping this tactics will ignore this tactical theme at the given level and get you a rating of lets say 2000 minus tactics of that theme. This habit of skipping will start a chain of ignorance and if you get a rating above 2400, you will have only done so by skipping most/all tactics of a certain theme.
In the end, you will not be able to solve tactics of 2000 strenght including the given theme most of the time and you will question your tactics rating and wonder where you went wrong. Worse is you will miss them in your game and you might lose to opponents you out rank due to a tactical oversight and feel like an idiot.
In short, skipping tactics is a terrible habit but only becomes chaotic if you use this technique and improve your rating.

I guess we should all team up and solve tactics in a row and we could have a challenge to see who gets the highest amount correct?!
Just an idea and I just want to have a little fun. :)

Oh, your the kid lol. That came to a surprise when I watched your first Tactics Trainer video.
Well, I only watched you try to solve the first problem. Honestly, it was terrible. The introduction was fine, I like how you speak. The camera and editing did not appeal to me. But the worst bit was when you attempted to solve the problem. You mentioned the Queen was pinned. Then you went on and said you thought it was Rd1 without explaining yourself or calculating and failed it a few seconds later lol.
Sorry for the review but if that's how you solve problem

How in Gods name was your Tactics rating at my level 3 years ago when your at the age of rapid improvement?

No no I take criticism .
Here's my problem. I don't know how to edit since I'm still only 12. I'm learning though. I do agree that I have to improve my commentary. That was only the first episode though:
Im still trying to get better at speaking correctly. If you watch my Chess Battles it's a bit better. But don't watch the first or second episode of that series. Actually, don't watch any of the first episode. If you watch the last TT video I did it might be better
THANK YOU BTW! I need as much criticism as possible to improve for you guys. And I'm not offended. Thank you.
Maybe only a slow thinker can improve in tactic trainer's blitz regime if you score a %80 +? Well I can improve infact I am going to start doing tactic daily again.
