Keep in mind too, there is no mad rush right now.
Be thoughtful and intentional in every action from here on out.
This is a marathon, not a sprint, and attention to detail counts.
Have you thought through your essays? Polished them to a high sheen? Will you be happy with them several months from now?
You want to put your best application together, and submit that best as early as possible, but that could be mid-summer, and you would still be surfing the first waves.
Getting teachers educated on what you will be asking from them for SA and nom apps, getting their contact info before summer, training for the CFA and getting that done, and done solidly, before next fall are the usual early tasks, along with prepping for nom application due dates.
