Next to zero with these marks. I would recommend to give your +2 exams again because even if you do some course after this Embassy will consider your +2 marks
you already have a negative profile because of your grades and backlogs. Also you have study gap of more than 2 years which makes your profile more weak. Sorry to tell buddy but the visa chances are very less.
Greetings
you have a good visa chance as you have good percentage but you might have a study gap problem in 2018 as it will exceed to 3 years and accordung to spp category you should have 2 years of study gap.
greetings!!
You have a long study gap and under spp category 2 years gap is accepted and in extreme cases 3 years.
You could give it a try but visa chances are less.

Doesn't fulfill the relevancy criteria. Your focus should be in course related to English(embassy's perspective) as the proposed study should match your previous major study.
