I REALLY NEED some advice. PLEASE help me. I don't know what my interests are.

My birth date is Oct 2005 (i'm 20 and will turn 21 this oct). I completed 12th in 2024 (79%), then I took a one year drop for JEE (failed and didnt get any college, then took bsc from local college and started preparing for CGL+CAT+JEE). This year I did not get college through JEE but I am getting admission in banasthali university in jaipur (will get any branch). I also thought of offline coaching for CGL this year but hostel is compulsory in college so cannot do that. Right now I am in 2nd semester of BSC (non attending college). I do not know whether to continue here or take admission in Btech (and also don't know which branch to take). I wanted a government job only but it is uncertain. I am not able to decide. I am feeling scared that if I start btech now the age for govt exams will pass (i'll graduate at 25 then i'll take coaching for a year and turn 26) and if any exam is not cleared then i'll get stuck.
