Skip the table of contents, not sure what you mean by references objectives but 13 graphs are probably about 6 too many. The Presentation should mainly be about your main findings. Not sure how you have calculated 34 slides as one every 45 secs as 30 would be 2 per minute for a 15 minute presentation.
Try to bring the number down by using bullet points and distilling the key issues. Don’ t put more than 2 graphs per slide – one per slide is better. A clear presentation is more likely to pass than one that is cluttered.
