Set yourself a learning budget and accept that blowing things up is part of the experience. It's not terribly expensive to buy a large stock of basic components. Sellers like Banggood offer assortments of resistors, capacitors, diodes and transistors for a few bucks. Arduino Nano clones are about $2 each on Aliexpress, so buy half a dozen. The Aneng AN8008 multimeter is more than good enough for student use and costs less than $25; a Daniu DT832 is perfectly usable for basic measurements and costs about $5, so it's no tragedy if you blow it up. You can find an old analog oscilloscope on eBay for about $50.

If you're getting into repair, ask your local thrift stores for broken electronics or buy a job lot of cheap broken stuff on eBay. If you can't fix it, you can always scavenge it for components.
