What do you mean by bad? Slow, stops a lot? That could just be your broadband speed, what is it? - I've attached link to a good test

You have to wait for the clocks to finish conne then it will give you 2 numbers, download being the important one. It can takes 20 seconds or more to finish, longer if you have poor speed.
yes when it's finished you will get 2 numbers in black boxes above the clocks. One will say Download speed, the other Upload speed, tell us what they say.
Are you sure you have those the right way round? If your download is only 0.3 ish you are never going to get a good show on youtube (or iplayer etc etc)
0.316, that is flatlining. Its metabolic processes are now history. It's off the twig. It's kicked the bucket, it's shuffled off its mortal coil, run down the curtain and joined the bleedin' choir invisible.
