I had posted about my disappointing 670 earlier. I think I'm starting to figure out what's wrong.
I asked a question a few minutes ago on the math forum about why a method i used didn't work. Except it did. I just made a blatant error (I had 20/25 reducing to 3/4)
I keep doing this. I don't know what's happening to me. I've done ~100 problems, and I made errors in simple addition, or just didn't remember a constraint (answer must be positive or something) on 89 of them. I feel like my brain is dying or something. I can't concentrate on anything for more than about 10 seconds, so I start reading a question, and when I go to do the work, any constraint or whatever from the first line of the question, I remember. Anything after that though, like on the second line or whatever, it's like I never even read it at all. It's enfuriating. I'm trying to learn concepts, but I read a line, and then another, and then by the third line in the quant guide or whatever, I can barely even remember the start of the sentence by the end of it, or maybe I didn't even read it at all. Somehow I'm memorizing formulae still, but when I go to apply them I NEVER get the answer correctly so I get frustrated and think I don't have a clue how to do the problem. Except that's not true, because almost 90% of the time I did have the write formula to apply, I just added wrong (like today I subtracted 41 from 60 and got 9). Then when I go back to check my work, which I started doing after I noticed this trend, I don't even see the error. I think "ok, so 60 minus 41 equals 9, yup that's correct". I'm doing this all the time, I misadded -1 and 1 the other day, 2*3, I had that equaling 5 or something. Even worse it's taking me 10-15 minutes per problem to even see the error. I have no idea what's happening to me. It's not burnout, I just took 4 days off from studying, and it's no better now than before. I hate this, I can't concentrate at all on the problems I'm trying to work on.
EDIT ;ASKDJ;ASDKJ;FLASKDJF;KLAKJDF;LAKJSDTK I JUST DID IT AGAIN. RIGHT AFTER I WROTE THIS.
x = 2^b – (8^8 + 8^6) for which of the following b values is x closest to zero?
I wrote it down on my pad as x=2^b-8^6*(8^2-1). should have been 8^2+1.
I think I'm dying or something, there's clearly something wrong with me. I can't even do basic math anymore.
EDIT: AND AGAIN. I had a problem with \(\sqrt{(k+1)}\)+\(\sqrt{(k-1)}\)
I tried plugging in 3 as an example, got 2 for the first part, then for the second part I got 2 as well...I completely forgot that after the 3-1 part I had to take the square root. what the hell is happening to me
