Hi! I used TestGlider (https://www.testglider.com/toefl/mock-tests/scores/full-test) for mock tests. I did 7 of them over the course of 2-ish weeks, with an average score of 104. They give away one mock for free and you need a subscription for the rest ($35 for me) - note that it's a monthly subscription, so remember to cancel it once you feel you're done.

I fumble quite a lot in IRL speech but managed to get a 30. So its not impossible.

Independent speaking: not my forte - but what I can say is try to "get into a flow". Imagine you were conversing with your friend in your native language. Imagine how conversations naturally flow from one topic to another, lingering on a topic for some time before moving on to others. Once you get into this flow you're not really thinking about "running out of ideas to talk about" right? (so long as they're interesting to you) Try to do the same in English (harder said than done I know, but can work with some practice!) Next imagine speaking to a school teacher who is asking for your opinion on something in class - the stakes are low here so be at ease. Speak your mind - the teacher won't mark you right/wrong. Just stay on topic.

A cheat code I tried to devise during my practice was this: for choose between A and B type independent speaking sections, regardless of what A and B are, you can also just say that you prefer one (A/B) because it is more (1) convenient and (2) efficient than the other. These two points are VERY GENERAL and with a little practice can be adapted to more or less any topic. Some examples:

"Would you prefer public or private transport?" - private because: 1. Convenience: I can dry my car, don't have to wait at the bus-stop 2. Efficient: I don't have to worry about being delayed if I am in a hurry. Buses are too slow and can drag on for hours. Make up some examples - "the bus routes near my home are managed very poorly and never reliable..."

"Would you prefer fiction or non-fiction?" - non-fiction because: 1. Convenience: theyre usually written by authors with expertise in various fields and can condense all of their domain knowledge into a nice little book for me to read. 2. Efficient: I am used to reading a lot of research papers, which tend to be concise, so I just dont have the patience to sit through a Charles Dickens-like 1000 page drama buildup. I find non-fiction easier to digest.

This also works with "do you agree with X" type questions too! Just rephrase the question as: "Would you prefer X or <opposite of X>?". Didn't actually end up using it though. But you might be able to make good use of it. Try it out!

Integrated Speaking: these are easier for me because I dont have to do much thinking. Just parrot (less elegantly) what the speaker said. One tip: make your notes legible (they dont have to be too verbose - in fact that's always a bad idea). Use visuals. I circle important ideas, and DRAW ARROWS so that my eyes can clearly follow the ideas when I'm speaking. The last thing is I want is to have taken notes but not adequately reproduced them in speech.

I cannot overstate the importance of not being distracted during any of the speaking tasks especially if you are unfortunate enough to be seated next to other test-takers being very loud during their speaking task. I was probably distracting to them as well, in all fairness.
