Yeah, good for you @fallonsteve291 for dedicating time to memorizing these scales, it WILL improve your dexterity, speed, and ability to improvise, so it’s time well spent.
All of @Slim’s advice here is RIGHT ON THE MONEY. The only slight modification I recommend is when you’re under 100 BPM try just increasing 5 BPM at a time (i.e. from 50 to 55 to 60 to 65, etc…) and then 10 BPM at a time once you get to 100. Of course any time you can’t quite keep up with a new speed you can try backing off just 1 or 2 BPM and see if you can keep up.
Another great #nextlevel excercise in this regard is double timing. So once you can play quarter notes at 100 for example, a great excercise would be put the metronome at 50 and first play long tones, maybe whole notes (4 clicks per note) or half-notes (2 clicks per note) and then once you’ve played the scale half-notes a few times, without stopping switch to quarter notes (one click per note) and then without stopping switch to eighth notes (2 NOTES per CLICK) and then go back down.
Also here’s a link to some of the other SUPER-helpful approaches to practicing scales that @Slim mentioned:
For #nextlevel from there, you can try half-timing /double-timing the excercises of 3 notes or notes skipping. And a step above that is instead of just ½ notes, 1/4 notes, and 1/8 notes, you can include 1/8 note triplets and 1/16 notes - that when things get really exciting.
It never ends! There are always more cool things you can practice. I could go on and on but I have a sense I might be making you a lil dizzy already? 
Remember, above all else, stay relaxed, and HAVE FUN!!
