I came here to see if using chegg was a good idea and it definitely is helpful. I am doing physical chemistry and for this course you need explanation to the textbook questions to understand the material and get a good mark on the exam. Purchasing Chegg is equivalent to purchasing a solution manual, but with all explanations for all questions available, so I definitely think its worth the money and this shouldn't be cheating - you are just getting a more detailed solutions manual. Plus a solution manual is usually $70, while using chegg for a semester is just $56.
