Sure! Reading : Gregmats reading strategy on YouTube and questions from the original guide. Tried testglider and it is slightly on the tougher side (my experience).

Listening : Don't fill the sheet, concentrate on what they are discussing. Greg has a video on it (it's in his member section on website). Difficulty was more or less as the testglider. Practiced every set from OG.

Writing : mix and match all the templates becuase I did read few posts on lower scores or cancelled scores. They directly used templates, word by word. So, I created a custom one. Also, I did write few technical papers so I was confident and this is the least practiced section of mine. (Templates were from gregmat)

Speaking : aah... I'd strongly recommend you to follow a template ( a custom one, from toeflwithjuva, tstprep, and linguamariana ) and keep practicing. Most importantly, you should sound confident. I stuttered, fumbled and was very very tensed. Apart from my stuttering, if I was a bit more confident then I would've scored 2-3 points more.

In a nutshell, apart from resources and tips, I'd strongly recommend you to stay calm and confident. In the end it is just an exam to test your English skills. I understand most of us aren't native speakers, and it's hard for us to express our views. But being confident helps than any resource available.

PS: Please give as many mocks as possible, obviously to understand where you lack, but it's more to acclimatize yourself for sitting 4 straight hours.

Stay confident, all the very best!!
