Since I'm over 60 I for sure have made more mistakes than you (just an assumption though) but I learned from them and use that learning to offer advice where I can. The membership of this forum do this daily, without recompense and with the intent of helping others.
All we hear from you is your 'struggle' - nothing positive, nothing helpful, nothing even remotely encouraging and, by your own admission, you failed to keep your notes (ISTR you said you SOLD them? - sort of sets the scene for the type of person you are really i.e. in it for the short term gains). If you want 'fake' cheers and shouts of 'go for it big boy!' you've come to the wrong place.
What's the actual pass mark for the exams? Is it important to pass or to get 100% in everything? One answer is reasonable and the other is ridiculous. A 100% pass mark doesn't mean you understand the subject 100%.
If you can't instil confidence in 'me' you're going to get no where trying to instil it in yourself.
Since you've previously took none of the past advice I'll take yours (for a change) - ignored.
I was suffering from mental health issues. I was naive innocent, out of touch with reality for almost 2.5 years of my life which happened to coincide with engineering college. Friends, seniors, relatives, parents all misguided me and as I was too naive I fell for the trap. I was very stupid as well. But that's past. You can't belittle me for it. I don't understand why people in these forums seem IDK what to say..what type, what type I don't understand. Are they failing to understand that I realized my mistake? The point is I am not the same person I was before and I keep on improving. My teachers shit the bed, so what, earlier I found excuses, now I use forums to clear my doubts. Most of the times I don't even need answer from anyone, I get the answer after I articulate an answer myself.
I was unlucky and stupid that it all happened to me. Nb choses depression, nb chooses mental health issues. While I am still suffering from them, I am recovering them...and I can feel that. I keep all my notes now. Very organized. Although we are poor and can't afford a study rack to keep those notes, I manage them in a cartoon like thing that comes when you buy stuffs from groceries and shops in bulk. IDK what they call it.
. That's why I made mistakes. I regretted it and moved on, no need to shit on me for making those mistakes at those point.
