My Way to L.N.C.T. Bhopal

I will write in both Hindi and English....

So today is the day i started my first Blog ... and recently i started my college life  too...

So lets start with college life.....i.e; college life experience....what you thought and and what you got.

(haha its happen with most of us....)

So my college...it's L.N.C.T. (Lakshmi Narayan College Of Technology). It is a college just by name...By rules & regulations and method of working its a high level school (not High Schools) an Engineering school.

Lets Start it from the beginning...how i ended up here in LNCT

I went to Kota in 2014 for engineering coaching. I took admission in Career Point. After 5-6 months i was clear about not doing further engineering study. So i thought to study BCA (Bachlor of computer Application). so after spending total nine months in Kota i returned back to my home. Here i had my class 12 board (BSEB) exams in feburary. I got total 73.2% marks in BSEB. so now the time was to look for a college offering BCA stuudy. I started searching and ended up searching some famous and some above average colleges. Since i was not able to spend lots of money. so i choose a college named DSVV (Dev Sanskriti Vishwavidalaya) Haridwar, with total expense of  rs 80000 per year. Since all the admission process starts in late may-june.All i have to do was wait, but the discussion and contradiction between BCA and B Tech (i.e; engineering) was still going on with my parents and family members. Some one says BCA is better, some one says B Tech is more better. I got confused too. But i was stuck to BCA.  

So for rest of story of ''my way to lnct''.... please visit tomorrow again.

thanks for giving your time

you can share your story of "way to 'your college'" too.. here.

It's CHANDRAKANT KUMAR thanking you again...
