Student Testimonials
Lidia Carney, DPSI Law Student (Portuguese)Lidia Carney, DPSI Law Student (Portuguese)
I did the DPSI online course with Helena a few years ago and this definitely put me in good stead for the future. Since I became a qualified interpreter I have worked on hundreds of legal cases, from simple court trials to complex murder cases, working in a variety of challenging scenarios. With time, I also went into translation and eventually took my Diploma in Translation examination. These days I do both activities. I am a member of the Institute of Translation and Interpreting (ITI) and of the Chartered Institute of Linguists (CIOL).I feel that the course definitely put me on the right track as a professional and it is a really good basis from which to start working as an interpreter. I can recommend it without any hesitation.
Aleksandra Hales, DipTrans Course (Polish)Aleksandra Hales, DipTrans Course (Polish)
The tutor was absolutely fantastic! She gave me detailed, constructive feedback and suggested which aspects I need to improve on. I cannot believe how much I have learned! The course was very flexible and the time between the sessions sufficient to complete the assignments... Constructive, detailed, honest, spot on! The feedback allowed me to develop my skills and work on challenges... The tutor was very experienced and knowledgeable about the subject. She was always very well prepared and organised. Very reliable and punctual. I cannot praise her enough! There was always enough time for my tutor to go through the text in detail. The online system is generally very easy to use... the course is really good!"
Silvana Veloso, DPSI Law Course (Portuguese)Silvana Veloso, DPSI Law Course (Portuguese)
At first I was a bit apprehensive and fearful about doing the course, but thanks to my tutor and colleagues I really enjoy it. Every lesson was a new experience. The modules were very useful for the exam and will be for my work. I was very blessed to have a tutor with such experience like Helena. Her way of explaining things was incredibly easy to understand.”
Stefania Greci, DipTrans Course (Italian)Stefania Greci, DipTrans Course (Italian)
I enjoyed the course very much and looked forward to my weekly assignments and feedback sessions. I worked extremely well with my tutor and found that the feedback sessions through Skype were the best format for me. Having enrolled on a similar course years ago, I found that receiving “corrections/feedback” through a written document instead made retaining what I did well and not so well during my practice more difficult. I found the DipTrans Online flexible enough for me. I was able to arrange regular feedback sessions with my tutor or reschedule when needed... I was always provided with in-depth explanations about my work. The tutor made also very clear the difference between something that was just a suggestion and something that was instead wrong and would have counted as a mistake in an exam situation. I had no problem in receiving an answer to any query either from my tutor or from the DipTrans organizers.
FM, DPSI Law Course (Rare Languages)FM, DPSI Law Course (Rare Languages)
Fantastic experience and excellent value for money. It met and exceeded my expectations in many ways... I often find it difficult to self-assess my own writing, so I appreciated the objective feedback from an experienced linguist. Helena (…) was extremely knowledgeable about the English legal system (…) It was clear to me that she genuinely cared and was willing to help, and it made me feel secure and motivated – something I value most when taking courses. It was my first time to participate in an online course. Before I started it, I couldn’t even imagine how it would work. I remember feeling a little nervous and uneasy on the first couple of tutorials. However, I gradually became used to the method and was quite comfortable and relaxed after a while (…) The Rare Languages class was harmonious and motivating. It certainly helped me to go through the journey which might have been daunting had I had to do it alone.
