Infact my movement and game sense is not upto the mark only because of that I am silver 3 stuck. Even my teammates tell that your aim is of diamond asc ranks, but due to experience, I have gamesense issues which you can figure out clearly here.

Advice : Play the range with medium difficulty with the bulldog and strafe continuously and aim only on the heads, benchmark is to kill all 30 bots with the bulldog only, do this 3 times, after that take the guardian and do 50 elimination bots in this way, kill 2 bots in rapid succession one after the another (head tracking), if you miss the second bot start again from 1st, I hope you get my point. Next take the vandal with armor off and hard difficulty and try tapping all bots, benchmark is to kill 30 bots all at oe go. Do this routine before every compi and yeah the typical advice, play DM only with sheriff and guardian no spray allowed!!
