I have considered that but I don't have the money for that as of now. And if I still don't improve with one I will feel like I wasted money
No improvement

I have been playing chess for a about a year now and still am stuck around 800 rating . I was told to study engames and tactics. I did this for a very long time and still did not improve. I tried analyzing my games, which did not work because how am I supposed to notice my mistakes when I lost the game , besides things like obvious blunders . I understand chess is supposed to be fun which it is . But not when you constantly lose and never see any improvement no matter what methods you try , any suggestions on what I should do is appreaciated .
What is your IQ?
... I was told to study engames and tactics. I did this for a very long time and still did not improve...
It seems from your other thread that you were told that just two weeks ago? Don't give up yet; that's not a very long time at all! The general advice seems to be that you should do at least 15-30 minutes of tactics every day.

You need to work on a thinking system. You need positional knowledge so you can break down a position into its individual units for each side and evaluate accordingly. Go by statics and dynamics. You may think a pawn center is an advantage for example but overesimate it because the opponent is better developed and can at best (for you) maintain equality by forcing one of your central pawns forward, blockading the hole with a knight, and chip away at the supporting pawn (e.g., e5/d4 with black knight on d5 then ...c5! and the e5 loses pawn support).
A not so concrete example but something to consider. A critical position arises after pawn moves or an exchange, this is when you make adjustments in your planning.
Without further ado here's a list of advantages to look for, not just for yourself but the opponent too:
Static:
- Material advantage
- Central pawn majority
- Passed pawns
- Weak opponent squares
- Superior pawn structure
- Better minor pieces for the position's needs.
- Queenside pawn majority
Dynamic advantages:
- Vulnerable opponent pieces
- Superior coordination
- Better central control
- Control of ranks, files, and diagonals
- Space "advantage" (The quotes are because while it can legitimately be an advantage in practice the cramped side could punch out and the advanced previously cramping pawns become objects of attack).

to the person that asked my IQ I have never taken the test and I don't think it is too relevant either

It is relevant. If you have a low IQ, that would explain why you are not improving.
NM Dan Heisman recommends repeating a set of simple tactics with common patterns until you can solve them entirely from recognition: http://www.chesscafe.com/text/heisman109.pdf

Link me to these sources pawn
Common knowledge. Intellectual disability is linked to lower IQ. When I find some sources, I will post.

Thanks for the link nen , and I obtain above average grades in school, but either way , I feel like IQ would raise due to playing chess, not having it be a needed thing to play. I'm sure theres a strong chess player with a low IQ or that has had one . And obviously intellectual disablility is linked to low IQ we are talking about chess though .

pawnstogo is just here to cause trouble; he hasn't even played any games.
I played many games on other sites and OTB. I am not causing trouble.

Nen is this a book that I need to download ? The link only shows 4 tactic puzzles, or is that the set ?

Do you know how to calculate? No good to study the endgame if you can't calculate.

Read Mark Dvoretsky's Endgame Manual.

Just check before each move that none of your pieces hanging.. That should take you to at least 1000

I was looking at some of your 15 10 standard games and it seems to me that the main reason why you are losing is that you are making obvious blunders like hanging a piece. I think for an 800 rating player, you should focus on avoiding making obvious blunders. Game like the one below wherein you gave away a piece 5. ... Nc4?? is an example of an obvious blunder.
I think you should also continue in playing the game even if you blundered a piece, such as in the game below. Your opponent is also an 800 player and is likely to also make a blunder during the game. Don't give up that easily.
