Help Me to Get My Degree

Hi this is Md Abdul Awal Luin. In 2014 I have passed My HSC ( higher secondary school Certificate).Then 2015, I have admitted to a Engineering Institute by given e admission test. My result was, 345 in merit position among the 7000 admission students.(only 500 student can get the chance to study for a very little amount of money).

But after one and half year later when my grandmother and grandfather had died ( they died after one another just 2 days apart) then i could not sit for the final exam in 2 subjects.Then i had some family issues which brought a very big problem That"s why i could not continue my study. Aftar 2 years later I want to study again. But the university can't grant this 2 years of study gap. That's why i have to study in a private University which is costly(around 4000-4500$ needed) and i(also my family) can't manage it.So I am here. Please help.
