ATCL or LTCL?

Dear all,

i m thinking to take Diploma exam in piano again.. indeed i took ABRSM Diploma exam.. i forget the name of the exam , it's actually the beginner grade for ( okie pls dun quote me on that, coz i really forget i took it like 10 yrs ago ) for diploma. i passed on the piano part but i failed on the oral part. ( augh... what a shame .. )so you know that it's a failed in total rite=P bec that exam needed both part to pass. ( is this exam the DIPABRSM? )

Since i want to avoid the Oral part which i failed on, i am thinking to go for trinity, but the thing is - i am not sure if i can take LTCL directly, or i should go tback to take ATCL first?

i could recall from my piano teacher that the ABRSM exam that i took ( actually i still huv all the book and pieces with me ) i can use those piece for trinity ATCL , is that true? also, can i use the same pieces to take LTCL instead? coz i heard something like ABRSM Dip the hardness to pass is same as the LTCL. in that case should i give myself a try on LTCL ?

thanks in advance=)
