nova master here, playing in SEA so I can't play with you, but so far I only play solo on ranked since I had no friends in csgo so I can give you some tips if you're playing alone in ranked. Remember to call where the enemies are, try to think how the opponent would move, learn to recognise signs (EG dust 2 playing as CT, T smoked ct spawn near mid door, push are likely to happen soon and prepare to avoid flashes and call where the bomber might be.) Silver are focus on their play and their spot only, you need to think of the whole map. And no cocky attitude even when you are carrying every game, it is demoralising and everyone won't admit you are good, you are just a high score douche. They rather kick you off anytime. No flame no rage only praise and commend.
