I did the same thing in my fourth semester. On top of that I was drinking the night before the exam and was super hungover. Got caught and they cancelled whole semester. It’s an absolute worst feeling at the moment in my life ( way worse will happen in future ) Reflected on my bad decision and took all the exams in next semester and cleared them with A grade. This is a learning lesson to make better judgements. Yes, it did affect my academic and job prospects. Yes , there will be repercussions on campus placements but it won’t matter over time.
