Student or Learner
I study hard but no progress yet. I am still a poor student. I want to express it correctly.
"I study hard, but I've made no progress yet." (Present perfect)
"I've been studying hard, but I haven't been making any progress."
"Although I study hard, I haven't made any progress yet."
"Even though I study hard, I don't seem to be able to make any progress." They are all natural. But you need "make progress".
"I'm still a poor student" is OK.
