As I've said before, I'm a returning flight sim pilot thanks to MSFS2020. I have no experience in flying an actual plane. I am trying to relearn everything. I thought about 14 years ago I had this stuff down, or at least a decent grasp on general procedures. Having come back I'm realizing I am a bit rusty. This time I come seeking advice on flight plans.

The first leg of my around the world tour is: KOPN to KSBO

Using Skyvector it plotted my course as such:
KOPN, FORBES, MCN, OTGUQ, CARYS, APELE, DBN, KSOB

Is this accurate? I'm assuming they are plotting along victor airways? It set my altitude at 8000 but I changed it to 2500. I'm also assuming with such small airfields that those vectors will put me entering the traffic pattern at KSOB?

My plan is to use each leg of my trip to focus on my technique and hopefully improve my flying skills. This is one aspect I've never been sure of. I used to cheat back in the day with a program I think was called, copilot. It would create all the waypoints, told me when to start my decent ect.

Anyway, I look forward to any advice, tips or tricks you can give.

I think I found my answer.
