Currently i am a kgs 13k, although i think i am lower since i am losing every single game pretty much. So i was going to ask how can i improve my games?

Note: I used to play often and was at a point where i could beat an 8k but probably a fluke lol. I've been doing life and death puzzles for like a year now but never really played any games with others.

This is a guide written by someone who studied in Japan with aspiring pros (insei):

Guide To Become Strong

I think it's the best advice I've seen on how to improve.

edit:
Another good article:

Are you or are you not playing against others?:) OC, you must play games. Also read relevant beginner books such as First Fundamentals and In the Beginning.

I havent played with others for like a year just started now and on major losing streak lol.

Ok, so continue to play regardless of your losing at the moment. Every losing streak has an end, especially if you acquire knowledge.
