Is it necessary to apply for a remedial class for the patent agent exam?

depending on your personal situation, if you have enough time to study and review, you will have a chance to pass. If you are too busy to find a learning method, you can sign up for a remedial class. I suggest you go to Pangu's patent agent training class. Their video course and self-made teaching materials are designed to improve the passing rate of candidates, which can save two-thirds of the study time and improve 5% of the results. You can decide whether to report it or not.
