If RC is a section you struggle on with timing (I used to need 50+ min) I started reading for fun before bed. It really helped me with my speed. Your brain is a muscle! You just have to train it to do what you want!

I would be interested in joining!

I found the same thing happened to me, I chalked it up to knowing what should be doing the second time around so there is some hesitation etc. Don't be discouraged, this entire thing is a long process and you're doing the right thing! Try smaller timed sections for practice ex: a RC passage (9 min~) LG (9 min~). Try and get that pace and then put it all together for a full section. I didn't time myself for the first few months of practice tests because I wanted to feel comfortable with the content and not discourage myself. GOOD LUCK!!
