Hey planning for Annapurna Base camp trek(solo) in Baishak

Highest altitude I have ever been to is 2,551 meter(Chandragiri Temple), felt completely normal.I did 5 hours long trek to get there.I have almost no clue except the way and I have watched some videos relating to ABC.

I hope there are tons of people here who know thing or two about trekking to Annapurna Base camp.I hope you could guide me....

I am also considering for Langtang trek solo....
