Yes, it is possible. Some people have done it.But my advice is to not to pin your entire hopes on this single target.

Even for my own masters I took bout 3 years plus, but then my case is not the norm. The things that hold or delay you is always the thing that is beyond your control. It's not like in Bachelor's where you study, do a bit of labwork and done.

For example, some chemicals/reagents that you need might be delayed and take 2-3 weeks to arrive instead of 4 days. Or if you work with biological samples, your rats suddenly died or your bacteria clones got contaminated. Then you have to start all over again and wait to get new mice, reinfect them and wait for them to grow etc. In my case I had to travel a lot for sampling into remote places so that took a lot of time as well.

The point is that when it comes to dealing with biological stuff, it's a bit more unpredictable compared to say, social science or engineering where you have more control over the subject of your experiment.

I'd say you can use 3 years as a rough guide or soft target, but don't drive yourself crazy pinning it as the ultimate goal. Besides, it's not really a matter of how fast you can do it (though it's good), but how much you learn and experience from it.

And the most important part is you gotta beat your procrastination. It can be very overwhelming you just can't resist procrastinating although you know time is your number one enemy. High self disciplined and motivation are needed. 

Yes. No problem. Got any title? and the research is basically re-search again and again
