I don't really agree with "just trying to stay on track" in the last part. There are certainly places that make you time around there.
I haven't driven Laguna for a while, but heres my take on it.
T1 is just a kink.
Arriving at T2, Brake HARD at just before the 3 board. As you brake start turning left towards the apex, this will kick the arse out and point the car more towards the middles, get on the power as early as you can. And use all the road you can. If you have to lift off then you've applied power to early. You want to find the spot that allows you to not take your foot off.
T3, a tricky right hander. Brake at the 2 board quite hard, the key is to not turn in to soon. Turn in just after the 1 board (pretty standard on Laguna) Get on the power before you go past the red kerb. Your wheel shouldn't actually touch it, just kinda brush it.
T4 doesn't require you to brake, just a lift at the 2 board and turn in at the 1 board. On the approach it helps to position the car as wide as possible and just throw it in and get on the power early.
T5 Brake earlier than you think (around the 3 board) and turn it at the 1. You want to get the car in early and hug the kerb. Get the power down as soon as possible.
T6 is one of the trickiest and most important. Brake at the 2 board quite hard and turn in at the 1 board. Do not hit the red. You should be full throttle before the apex. As you go up the hill wait as long as you can before you shift to 4th.
T7 is a little kink to the right. But you start your braking at that point.
For T8 (the corkscrew) Brake hard just before the 3 board. Things get iffy around here. Turn in quite late and apply the throttle as your heading down hill. Turn to the right and keep the car to the right.
T9 is pretty tricky. Turn in is quite late, requires a lift and maybe a tap of the brakes. As soon as you see the apex your aimming for it. Get the car pointed there and floor it. The car should just kiss the apex and track out nicely.
T10. Approach from the left, Brake at the 2 board, and turn in at the 1. The car will scrub of speed allowing you to take it a lot faster then you might think. The camber is also useful for you. Get on the power at apex and the car should just run up to the outside kerb. It may take a while to get used to it, but it does do it.
T11. Hard corner, as you can win it or lose it here. Brake at the white line, between the 3 and 2 board as hard as you can. Get the car slowed enough so that it will grip and not just understeer. Your aim is to get the car pointed straight enough that you can just mash the throttle at the apex. And thats Laguna in a nutshell.
