ap classroom and ap chem

the aps are approaching the nervousness is kicking in, i have been using ap classroom consistently throughout this year, i watch the daily videos, do all progress checks and soon after i finish unit 9 i will start with the review videos that came in recently, id say ive had a great experience i usually get good marks on my progress checks,mock exams and frqs. the videos are clear, but ive seen people use crazy amounts of resources to earn a 5 and barely mention the use of ap classroom other than the practices available, am i missing information by only using ap classroom? if so, what should i study on?
