Valid to fly or not

[Aware]

Not flown much due to obvious reasons.

Expired Class 2 was renewing my Class 1 but need to complete a stress ECG.

I have a medical dec, my SEP expires end of September but would like to fly hours to meet the 8 hrs needed. I'd like to renew IRR I know I can't use it until class2 is renewed but thinking I can fly the renewal test.

Thanks,
