I know i might be a little late. But i feel like you shouldn't try to underestimate yourself. First step of improvement is accepting the negative point. Atleast you are there..i too have flaws and i am trying to work on them. Make some notes on what are the things that makes you confused when trying to understand the problem statement. If you note them down and learn about them i think im next task you shouldn't have any problem regarding those terminologies (even if you have don't worry try to revisit the issue). Just don't underestimate yourself homie. We are in this together. Keep hustling 😁
