This was my 2nd attempt, in my first I had 790... it took me in 7 weeks in total.. the resources I used was:
A course by the learning people (4 courses for £2,000/$3,000, A+ N+ CCNA and MCSA including unlimited retakes on the exams as long as you pass the mock exam by 90%) it includes online support live chat with tutors, daily email questions, and labs
CBT Nuggets for the areas I didnt understand
Boson Labs
Udemy
Live lessons (which was awesome also)
Thank you for all the support on this forum
