Why do I get negative rating in Starters contest?

I only participate in starters since I am very new to coding and a learner. I solved 4 questions in Starter 27 and did not do any malpractice. Each and every line was written in my VS code the total participants were ~6780 and my rank was ~3200. I compete in div 4 so I don’t think that this is very bad however I did submit a considerable amount of wrong submissions. I dropped my rating by 104 points. Please help me and suggest ways to get a positive rating. I am aware that the rating is based on the performance of other coders’ of similar ratings but still don’t think I did that bad. Please help
