I hope you don’t accidentally mix them up and use those grease pencils on your iPad

I used to do the same when I was a VFR student, put a layer of plastic on the VFR map and write down everything there. Later we moved to an airline style format which we needed to complete during flight and which was then checked and archived for 3 months.
To the OP, this is a quite standard format of what is used in the real world for (commercial) IFR flights. You can see there are spaces to write down ATIS and ATC clearance and it has the filed IFR route right there already.
Everybody has their own system to abbreviate and write down the clearance. I usually use the following:
Flight-plan route = FPL
Altitude 4000 ft = A040
Flight level 90 = F090
Squawk 1234 = SQ1234
Runway 22L = R22L
Heading 360 = H360
Speed 250 = S250
QNH 1020 = Q1020
Left / right turn = LT / RT
Frequency 119.100 = 119.100
Departure slot 12:00 = TSAT1200 / CTOT1200
For the SID I normally write down the first letter and the suffix and I’ll know enough. Usually you have some idea which departure to expect anyway. For ABTAL 4H departure I would write down A4H.
Example:
N3N R22R A040 Q1020 SQ1234 TSAT1200
Meaning:
NEPEK 3N departure, runway 22 right, after departure climb to altitude 4000 ft, QNH 1020, squawk 1234, target start-up time 12:00.
Everybody has their own system for writing down clearances, I have also seen pilots use arrows to indicate climb, descent, left, right turn. As long as its clear and you use the same system consistently.
