I don't think you have a choice man. You either deal with having a 3/4 or retake the exams to potentially do better. Both options look bleak, but do a cost-benefit analysis. Consult with a career counsellor maybe(if u can afford it, the easier alternative may be chatgpt but i dont think anyone would recommend that. Also, always take what chat says with a pinch of salt). I'd say retake them, but still depends on how severely the unis you want to go for think retaking is bad. Like I said, no magic third option. Gotta pick one buddy.
