Flying IFR and flying IMC are two totally different things.
When you timebuild IFR then it would help if you do the following:
- File an IFR flightplan and print it out or otherwise keep a reliable record.
- Ask the flight school for a printed receipt for every single flight you do.
This will allow you to put three documents next to each other,
Here is my logbook,
Here is the flightplan filed with me as PIC
Here is the receipt I paid for this flight.
