Which will TESC accept- letter grade or number grade on Transcripts evaluation?

Hi to all members. I have finally decided to follow the wise counsels given to me here on this forum. I have contacted all the previous institutions I attended to request for transcripts to be sent to the World Evaluation Services so they can evaluate them and forward them to TESC. This way I will know where I am and what needs to be accomplished towards my TESC BA Journalism degree. Now, I was wondering whether TESC will recognize transcripts where only letter grades are represented. For instance, all schools in my country usually record (on transcripts) students letter grades in formats like: EGL 101 A, MAC 201 C etc. Of course on the schools records, there will be letter grades available too. I was wondering whether TESC will accept such grades or they will be particular about seeing each number scores. Of course I know I could contact TESC to find out but I am relying on the experience of forum members who are used to TESC system or who have transferred credits to one of the Big Threes before. Could anyone please let me know if it is okay to request transcripts where the grades are written as A, B, C or D or I should ask my school to include the Number grades such as 65, 80, 90 etc? Thanks as I look forward to your usual kind responses.
