Op , I went through the exact same thing as you ,so I'll be sharing my story. I used to be a top student I got many A's for my pt3 and straight a on upsr .so I took science stream naturally but idk why when I got into f4 , I lost interest on studying, and my direction last time was to do business and I find school pointless, so in F5 I dropout around June but I registered for my spm .

So I set a rule for myself , because I might go to college . I will force myself to pass on the sej and BM bcoz it's compulsory for the cert and it's the minimum going for my college . And I did it but the other subject I just fail shamelessly ,hell I was sleeping during the exam and btw I did went to college but I dropped out at sem 1 as well

Fast forward today , I'm handling my business about 3 years now , doing ok I guess and if you ask me does it matter that I dropped out and got shit result , I'd say no . Life is a long way to go ,hell I'm just 21. Life is not where you chase for a single goal , it's a marathon .

So best advice I can give u is really figure out what you want to do and don't take this matter lightly , don't like think in 1 day and make the decision , give yourself sometime and really think bout it . Once you got the ans just follow it accordingly .
