I have been using the training resources from TREC for several years now and I must say they are excellent. The materials are comprehensive and up-to-date, and the online courses are easy to follow. The content is presented in a clear and concise manner, making it easy to grasp even complex concepts. I highly recommend TREC to anyone in the environmental community who is looking to expand their knowledge and skills.
