Quizlet works great even with vocab, grammar
, reading comprehension. I'm not certain about the math on quizlet. however, i did purchase a book last year by Mosby Elsevier, HESI evolve reach-Admission Assessment Exam Review-2nd Edition book. And between studying the math step by step there and watching YouTube videos online in simple steps, that helped me. I just passed my HESI entrance exam today!! Just study your math basics, addition, subtraction, division, fractions, percentages; conversions from decimal to percentage and vice versa, ratios...you should be good to go!
One piece of advice you don't have to try to memorize everything it'll just stress you out. take your time but don't stay stuck on one topic...move on and focus on your weakest subject. You'll get in don't worry. If I can do it, so can you!!
