Is that the PMDG 747 v2 you have?
Learning to fly a A320/737/747 is a huge learning curve and clearly it looks like you're just starting out. You dont GPS your way there, you should not have got GS at 1.500ft and lets not talk about you doing 93Kts at the end of a very long runway.
Learning is a huge undertaking and very rewarding one. So I would suggest a few things to help you on your way. Stick to the 747 as boeing's are easier to learn than Airbus's and they don't mix well.
Youtube is your friend here, do a search for tutorials on the FMC/FMS, learn about SID's and STAR's, there how to start a route and end it.
You need to learn how to use Simbrief or buy PFPX for your flight planning.

Here is a chart for 18R (below), if you look at it, you can see the GS interception height is 2000ft not 1500ft . That's after you have flown the right STAR to get you there from SUGOL. That's a different chart. You will see on the chart were it says SUGOL it says IAF that stands for initial approach fix, that's where you start slowing down and follow the STAR. The chart at bottom. Your STAR would be SUGOL3B. See! its easy really, well once you know.
Good luck and enjoy the learning, like I said it is very rewarding to start a UPS 747 up from cold and dark and Park it up after your flight. Your default Schiphol looks nothing like the FT version. Highly recommended imo about the best airport addon out there at this time.
Good luck and Enjoy!
The screen shot of the 747 is very nice the one of 18R is painful on the eyes but if you buy FT EHAM you will see why
