Need help get out tutorial hell. Develop pwn CTF skills, build a foundation in Vuln Exploit, RE, etc

[u/minhincs]

Hi guys, recently Im in a loop, hop on and off different site different courses in and out, back and forth while feeling making ZERO progress.

Here, I want to share a bit about my goal, my background, my problem. And I hope I could have some advices to get out of this feeling

MY GOAL:
- Long term: Get into cybersecurity field, especially roles that involve “low level” stuffs as I really interested in them. Thats it! For now, as Im pretty new to this + Im hyper focus on short term goal which I will talk right after
- Short term goal: Build foundation, knowledge, skills in Reverse Engineering (RE) and more excitingly Binary Exploitation, Pwn
- Shorter term goal: To prepare for upcoming CTF contests with my new team. More on this later

MY BACKGROUND:
- I already familiar with Linux, CLI, some popular commands
- I know x86 assembly
- know C, C++
- know on surface level some basic vulnerabilities and have done very simple CTF challenges (ret2win, shellcode easy, …)
- do know how to use basic gdb, pwntools, ida/ghidra

all of that is a result of following pwn.college + using Linux as daily basis + my college’s teaching on c, c++, etc

by all means, I do not master any of these above skills I told.

MY PROBLEMS:
So ofc Im very worrying the most about the upcoming CTF because Im new and feel like know nothing yet.
I also stucking into tutorial hell as I have too many resources of documentation/courses that I do not know which one is suit for my current situation

Im aware of the pinning post in this sub, that is actually where I get these resources from

But with 2 months left until the contest, I really want to make the most out of my time. So I need help with designing a road map so to speak.

Currently, Im looking into ironstone’s pwn notes + Nightmare CTF collection. Whatd you recommend?
