I took PTL1 with Ilse and Martin because Cathy Kinnaird mentioned in another class that they were doing an excellent job. I had already taken this class in another school, I am already an analyst, so it was just for me, and it was a pure delight. Not only the provided information was amazing and beautifully explained but you could really feel the love for HD and what they do is so present in all the knowledge they transmit. I really enjoyed it and I look forward to take more classes with them. Thank you so much Ilse and Martin, you are wonderful!
