Guild Wars 2

So … can i ^^?

I believe you can get some of them, but I think you have to complete it on normal mode to get all of them.

Scholar requires normal mode. Baubles, weapons, and hidden rooms can be done on any mode. I believe that the two requiring you to not die and to not use health potions can be done on any mode.

Also, the achievement for avoiding the plants in zone 3 can be done in infantile mode.

I did all of them in infantile mode except for the achievement for completing the level which requires normal mode.
