I want to get into nus CS one way or another

Currently im a poly y1 student( ie starting y2) and im doing cyber security and digital forensics. Honestly my gpa is kinda cooked im holding a cgpa of 3.19, but the thing is its not cuz im not good at my course ive just been playin too muchand i dint submit like a lot of work n what not but i still pull off A's cuz like i said, im good. im proficient in java ,c++ ,c ,c#, JS , some level of knowledge in python, and ofc backend dev and front end with html css and bootstrap. Okay comming to my main reason for posting this is i looked into my options on how i can get into this course. first i gotta bring my gpa up ofc lol and i know i can push to a 3.6 ish realistically speaking, with that gpa my options were either ABA or going into like info sec or like CE than trasnferring to CS in y2 in nus ofc. for ABA my portfolio is already pretty aight i have a year of combined interning experience doing AI pentesting and also general networking duties( maintaining / installing network infra for my company), and also i have a bunch projects with my main one rn im working on rn is an operating system im tryna write. I do hope i can do more ( also finish this project ). im curious would this be enough for an ABA application. and if not is it actually possible / fesiable to do a course transfer. please advice and feel free to diss me.
