Frankly it all depends on how u present ur case and ur luck. I have seen few ppl geting visa with 15 backlogs and have also seen rejection without any valid reason.
make ur case strong. explain as much as u can in ur SOP.
Colleges under SPP accept 9 back logs. As long as you have less than 9 back logs and you have shown improvement in the final marksheet, it should be ok.
