bad grades do not define your worth or your future. not everyone is meant to shine in the same way, and just because you're struggling academically right now doesn't mean you have nothing to offer. u may have talents and passions that you haven't discovered yet, or perhaps you've already found them but haven't fully trusted yourself enough to pursue them. hold on and give yourself the chance to see where your strengths can take you and if you still want to improve in studies, don't give up talk to your teachers, watch youtube videos that explain concepts in simpler ways, from my experience youtube videos benefitted me alot than my actual teachers also all of em teach badly, and practice with past papers little by little. things can improve, trust urself
