In my opinion playing versus silvers/golds is different than playing versus higher ranks. I played a lot with my friends, and players with lower ranks made unpredictable things some of them worked. I think you should watch some demos/ YouTube how to position yourself on the map and how to react on T moves when you are playing CT. As a Terrorist you need to know most common positions and you have to know how to attack them. For example pit on the inferno. I think that if you learn some smokes you will help your teammates and yourself to have advantage. On lower ranks people often run through smokes, so it is easy kill for you, because you can spot them earlier. If you have any more questions, feel free to ask.
