Rather than just drill holes in the sky, it can be valuable to spend some time in the training area going through practice emergencies. Some things you're only going to be able to do with an instructor, but there's quite a lot of value just going through solo 'thought experiments', if you like:
1. Do HASEL checks to ensure traffic clear, carb heat on if needed etc
2. Think of an emergency - any one, spring it on yourself eg "I hear the engine rough running", or "my TR chip light has come on".
3. Aviate, navigate, communicate - fly the aircraft; turn for wind and locate a suitable landing area if appropriate (or start tracking back to a suitable airfield via good forced landing areas if that's the appropriate action), give a distress call to yourself over the intercom (frequency? content?); set the aircraft up in an appropriate flight profile (if you would enter auto in the real case, don't, but while looking out for traffic enter a normal descent to give something of the sense of urgency); warn imaginary passengers; go through simulated emergency checklists and so on.
A lot of good practice can be safely had by just running scenarios.
4. Keep an eye on minimum heights and go round in good time.
