I might have dysgraphia or dyslexia.

Hello. I am Bikash. I'm from Hooghly, WB. Since very young age I was weak in studying, even simple maths was tough for me (still is), I commonly get confused with right and left commands and my handwriting is very poor. Now i am in college final year and I failed in my 3rd semester due my bad handwriting cause my teacher couldn't understand what I wrote but my friend who copied me passed and teacher said when she checked my paper it was actually correct and I passed but it was too late. I told my one of friend in Portugal she said I probably could have dyslexia, I did several tests online which concluded that I have dyslexia but am still not sure. I didn't even know that anything like dyslexia exists. I'm attaching a picture of my handwriting. I wrote it calmly and it's best I could do but in exams it's even worse. It's always been like this. No matter how much I try my handwriting never improved since my childhood.
