The 23-year-old secured her London 2012 place at the British Gas Championships in March after setting a new English record of 2:26.63 minutes to win the 200m breaststroke.
However, that followed on from heartache in the shorter 100m event at the Olympic Aquatics Centre where Tadd finished second and more than a second outside the qualifying standard.
Tadd will have one last chance to qualify for the 100m breaststroke with the ASA Nationals at Sheffield's Ponds Forge in June acting as the last chance trials.
She won't be making drastic changes between now and then but Tadd admits she is determined to make the most of the opportunity and ensure one becomes two this summer.
"My training will stay the same right through to the Olympic Games now. I won't rest until the second trials where I will give the 100m a shot and see what time I can do," said Tadd.
"It will be pretty similar to what I did from Christmas up to the trials with maybe a few tweaks to drop the couple of seconds that I need to qualify for the 100m.
"I thought I did pretty well at the British Gas Championships, especially my breaststroke. I did a medley event, which was not so good and it did get me down.
"But I just had to forget about that and concentrate on my breaststroke and I managed to qualify, which is what the aim was all along.
"A home Games means everything as it is probably the only one I am going to do. I am very excited, trying not to think about it too much yet, but I can't wait to experience it all."
Tadd spent last week, along with the 37 other London 2012 qualified British swimmers, at the annual national squad camp - training in the pool at the Olympic Aquatics Centre.
And Tadd is adamant, regardless of what happens at the second trials in June, the benefits of the British swimming team's London get-together will be clear to see come the Games.
"I really enjoyed the camp. It was good to see what the different coaches do during their sessions and it was just good for bonding," she added.
"It is really good to get together with the other swimmers, we are such a good group, we all get on and training with other people is really good."
