Business - Handed in controlled assessment

I have finished my business controlled assessment and handed it in.
However I did not finish all of the work !!!
I finished my research and analysis parts but not the evaluation.

The evaluation = 8 marks
analysis = 12
presentation = 8
research = 12

and I wrote an intro to my evaluation and wrote 3 paragraphs to rank 3 out the planned 4 factors in order of important.

I did not write a paragraph for the final ranking paragraph and I also missed out the last paragraph which was meant to be the overall conclusion.

Will this effect my grade ??
What's the highest possible grade I could get now ???
What are the rough grade boundaries ???
