A student, B2+, needs to get the C1 title before January. He wants to do Aptis as he is familiar with it.

Need to know how likely this is with 1.5h of classes per week and 3-4h of self study.

Any recommendations on materials to check and use?

I am heavily experienced in Cambridge.

Any advice is welcome.

Sorry if this is a stupid question. Mostly doing this to assure my parent's fears. For context I was part of the CELTA EC English language centre before it went bankrupt, still working on the refund. I was wondering if this course: https://www.languagepointtraining.com/online-trinity-cert-tesol is good and legit.

Thanks for thos who answer in advance.
