M25, 4 years gap due to govt job prep wanting to get in corporate. Please give realistic advice.

I have 5-6 hrs everyday for next 4 months which skill I can learn which can land me a 25k p.m (minimum) paying job in Mumbai. I have a 4 year gap due to govt exam prep. I am a bcom grad but now due to govt prep I don't have much knowledge of my degree + I passed out in 2022 during Covid so anything I have to learn I need to start from zero. Knowledge I already have is MS office, advance excel + decent english (don't judge plz this is all I have now)

Are there any realistic options for me

Or should I prepare for Mba CET/Cmat targetting a B school next year ?

Please help.
