Sorry for that 
It was really not obvious from the translation that this needed to be in ても form. Now that I know the answer, the Japanese makes sense. But it’s hard to get this Japanese just from the English.

Thanks for informing us about the issue!
I fixed it so that there should be no confusion. What do you think? 
The “remember about conjugation” hint? Can’t say it would have helped. But I can’t think of a better wording for the English translation that would tell you to use ても form.

Just wanted to say that I really like the note next to the caution icon:
…as it explains how its composed in terms of other grammar (albeit briefly), as I had wrote about a while back in a feature request.
I’m hoping this means I can expect more in the future ? 
I’m not sure if it’s just me, but I find the title of ～ようとする is a bit confusing at times.
Wouldn’t naming it “Verb[ volitional ] + とする” be much more fitting instead?
@Pep95 Sounds much more fitting! I have updated the title of the grammar point to match your suggestion. Cheers!
What’s the real difference between this point and ようにする (n4, lesson 7)?
The general answer from Stackexchange and HiNative seems to be that ようにする follows the second definition on Bunpro “to make sure that”, whereas ようとする is something you’re going to try to do. Perhaps it’d help to think about the N5 point にする to remember the difference.
As I understand it, ようにする is usually attached to habits or larger end goals that you are trying to achieve. ようとする is attached to some effort that you are struggling to do.
ジムに行くようにする。I’m trying to go to the gym. (I’m trying to make it a regular habit, but I just started.)
ジムに行こうとする。I’m trying to go to the gym. (…right now, as we speak, but the wind and rain and traffic is making it impossible!)
