Namaste Bharat!

Namaste Bharat!

Mera naam Bruce hai, Mai America se hun, mujhe Bharat bahoot pasand hai, Mai pichla saal bharat mein tha aur agla saal bharat aata hun, mai thoda Hindi maloom hai par thoda madad chahiye sudhaar ke liye

Dhanyavaad!

Mujhe bharat bahut pasand hai (you can replace 'oo' with 'u' when spelling 'very' (bahut) in Hinglish. I won't call it a mistake. I'm only trying to help you be able to pronounce the word correctly unless you were not meaning 'too' when saying that).

For your next sentence, written below would be a better structure with explanation.

Mai pichle saal bharat mein tha aur agle saal phir aunga (Youd end saying words pichla and agla with letter 'e' as 'agle' and 'pichle' when referring to a year (previous or next) the way you phrased it gives a different meaning that you will learn later.

From a native Hindi speaker standpoint, I wouldn't repeat saying Bharat there as I'd try keeping it as natural as possible so you'd say 'phir' (again) instead of mentioning it over and over. for example you wouldn't say in English - I was in India last year and I'll come to India next year (hope you understand my point)

You would add 'unga' to verbs when referring to things you will do in future. For example - mai aunga (I'll come), mai ek kitab padhunga (I'll read a book), mai bazaar jaunga (I'll go to market) etc.

Mujhe thodi Hindi maloom hai par thodi madad chahiye sudhaar ke liye. (With the word 'mai', the same sentence can be written as 'Mai thodi Hindi jaanta hun')

Languages in Hindi are feminine so you'd say 'thodi' before Hindi. Also, for the word 'madad' that sounds feminine so you would say 'thodi' madad. Use 'thoda' for for masculine things.
