Yeah, That's why i can't learn biasing and oscillators properly .....working in stimulator shows error and are not real....!!
Of course you can. Up to a point.
The learning part you are going to get from books, the internet, anyone around who knows.
I'm not sure what the problem with simulation is. I have used LTSpice from Linear Technology. It's free and despite being a Windows program works perfectly under wine on Linux. I have played with many oscillator circuits in LTSpice. http://www.linear.com/designtools/software/
As for practical experiments I'm no electronics graduate but as far as I know biasing is a purely DC activity. Getting all the correct voltages/currents to the correct places to ensure the transistors have the right conditions to operate. So no scope required just a multimeter.
Not sure what frequency of oscillator you are hoping to build but for audio work you can just plug the thing into the sound input of your PC/Laptop and find some free software to display the waveform. There are lot's of programs out there that will display waveforms and do Fourier analysis if you want to know about distortion in your signal.
I built my first oscillators when I was about 9 years old from a Philips Electronic Engineer kit. I knew they worked because there was an amplifier and a speaker to hear the output.
Some years later messing with digital circuits (TTL) with no scope I managed to debug things by detecting signals with a one transistor amplifier and a small speaker. This required slowing the clocks to get an audio frequency to detect or running higher frequencies through a divider chain. It's surprising how much you can check out just by listening to it.
Of course if you want to go to higher frequencies you might eventually need a scope, but don't forget that form many years amateur radio enthusiasts have been building transmitters without scopes and often above the frequency range of available scopes.

I'm sure all the colleges and higher learning institutes have oscilloscopes?

You are right i should try things normally..........!!
soon i will back to work after small rest..!!
Thanks
