The 18-year-old impressively ducked under the Olympic 100m A standard at the Sparkassen Gala in Germany on June 2, clocking 10.08seconds to become the fastest British sprinter this year.
However Gemili is determined not to let such a performance distract him from the world juniors and he intends to compete at the trials in Bedford this weekend - the England U20 Championships.
Gemili is the fastest junior in the world this year, his 10.08 well under the Barcelona qualifying time, and to guarantee his World Junior Championship place all he needs to do is finish first in Bedford.
And, having trained all year to compete in Spain, that's what he wants first and foremost.
"There is a possibility of me being exempt but I want to go and show what I can do and make the team by doing the junior trials because it's my own age group," said Gemili.
"The world juniors has always been my main aim this year, it's what I've been training for, so I'm focusing on them and then I will see how things are going.
"I've got a more realistic chance of doing well there too, but still it would be a fantastic bonus for me to make the Olympics at 18.
"The world junior trials are only a week apart from the Olympic trials so I'll have to see how I feel too. My body will still be recovering. However, I don't want to go to the Olympic trials and be half-hearted and not at my best.
"For now I'm just looking to get as many wins as I can under my belt. I've got a lot to learn and there's still so much that can be improved on.
"I'm just going to go and do my own race, stick to my plan and do what I need to do. I just want to keep progressing the way I have been progressing."
Gemili's remarkable story has drawn comparisons with Mark Lewis-Francis who similarly burst onto the athletics scene at a young age before opting to compete at the World Junior Championships instead of the Sydney Olympics in 2000.
Usain Bolt has even weighed in on the debate urging him to think hard before making his decision - but Gemili is just happy to even be mentioned in the same breath as two of his heroes.
"It's great that Usain Bolt is saying things like that because it shows I have put my name out there," added Gemili. "But I'm focusing on myself and nothing else. I want to do the best I can.
"I haven't spoken to Mark Lewis-Francis or got any advice from him yet but I know what he did and that his situation was similar to mine.
"It feels great to run quicker than all these guys I used to look up to. To be on a similar level to the people who inspired you to run is unbelievable."
