Text Guide:
The first time you can access this Mission is just after playing the third mission in the game which was "Priority: Palaven" where you had to rescue the Turian Primarch from Palaven's moon called "Menae". Warning: If you progress too far into the story, you won't be able to play this mission again.. unless you start a new game. After the third mission, go back onto the Normandy and talk to Specialist Traynor. She will be to the right of your Galaxy map. She'll ask you if you can help rescue the students at "Grissom Academy". Your first response should be "I'd like to help them." After that, go onto your Galaxy map and enter the Petra Nebula where you can start the mission. After you complete the mission, the Achievement is yours.
Hope this helps! Thank you.
