Indeed Allah knows what is best for us, but can you direct me some duas or amaal, for financial problem, my studies and for my marriage too?
If possible?

Please recite Ziyarat Aashura for 40 days. If possible recite under open sky followed by Dua Alqama then 2 rak’at namaz of Ziyarat and ask your hajat. Please fix one particular time every day you recite all these at same. Inshallah your Hajaat will be fulfilled.
