I highly recommend Spanish Marks. I found the company by accident, as i was working on my Spanish during the lockdown, but not able to speak to anyone, and I have been highly delighted with my lessons. I am an English Language teaching professional - I have been teaching English all my working life, and working on English exams, and I have been really pleased with the service I have received. It is really easy to book sessions - I opted for the block of 20 lessons - Rustom replies promptly and arranges the time with Gabi, my teacher - sometimes I just have one lesson a week, and sometimes more if I can fit them in - I just have to remember that as she is in Guatemala, so I need to book lessons at a sociable time for both of us! My teacher is extremely well informed, pleasant and patient - it is straightforward to explain what I need, and the lesson concentrates on those needs - then there are also support materials available online for me to use. In my case, my main concern has been fluency, as I need a lot of practice in speaking, which I can't access elsewhere, and Gabi gives me the opportunity to speak as much as possible, so that I can gain confidence and communicate more efficiently. In addition, when I make repeated errors, she makes grammar notes and worksheets available for me, and I can go through these with her during the lesson if I wish. The lessons are extremely reasonably priced, and at present it is possible to book lessons at quite short notice - in addition, it's possible to change the time or the day of the week you have your lesson(s), which is useful if your'e busy! I hope that you will enjoy your lessons with Spanish marks - good luck!
