Internal Assesment help!! Bio!

Guys I was just finishing off my IA for biology HL and I wanted to see if I had all the points for each criteria and so I looked on clastify(a page with exemplar IA with comments if you're unfamiliar) and I found basically the SAME investigation that I did but with another plant with close to the exact same %s of the SAME acid that was tested on the plant. I looked through it and it was basically the SAME as mine, except the data and the information that was worded differently. The methodology and the structure is EXACTLY the same except the end. I'm worried now because it's super similiar and I don't want to redo my experiment...What should I do? Even our questions(titles) are nearly the same except the plant name. What should I do? Please help!!
