For DI, practice from OG. For first time, practice untimed quizzes (20 questions) and when you have forgotten the answers, practice the same questions again timed (20 questions).
For Quant, you could either use OG for easier to medium level questions. For higher level questions, go for GMAT CLUB
FORUM QUIZ or
GMAT CLUB TESTS. You can try giving quant sectional tests everyday.
For CR, use
Forum Quiz, try quizzes at different difficulty level questions as you improve.
