Hi,
Since JB based instructed is still blocked - how about taking a cheap flight to Clark, Philippines and getting some of the basics done there over a couple of long weekends? Rentals are nominally in US dollars, so in your favour while the S$ is so high and instructor time is good value.
The "season" is opening up soon, mid- December onwards is usually flyable most mornings.
P.M. me if you want contact information
