Hellow~ When I change a simple sentense into a complex sentense, I don't know whether I shoud use future tense in a subordinate clasue. for example, I am sure of his winning the game. (a). I am sure that he wins the game. (b). I am sure that he will win the game. I have hope of going to the university. (a). I have hope that I go to the university. (b). I have hope that I will go to the university. which one is gramatically correct? or Are all the sentences used with the same meaning in common life ?
