Thank u Kelvin ,Yeah the CV has to be with formal vocabulary.

Hi Leidy, Good question. First, regarding past or present tense. If this is your current job, then use the present tense. If it’s a past job, or related to past tasks that you no longer do, then use the past. I would write this (assuming that it’s your current job): Teach biology to at risk and disadvantage groups of adults and young learners. If you think there’s value in adding some examples of which types of learners, then this would work: Teach biology to at risk and disadvantage groups of adults and young learners, including those affected by drug problems, those with intellectual disabilities, and single teenage mothers. Without wanting to get too technical, these examples are for a ‘responsibilities focused’ CV. In other words, one that explains simply what you do. I recommend some key achievements as well, to demonstrate your successes. This could be something like (as an example): Designed and delivered a teaching initiative in the XXXXXXX neighborhood, to single teenage mothers, with the aim of helping them find work. The above is an example. Think of your main successes in each job; those projects that you have been a part of that really stand out. Good luck with your job search. Kind regards Kelvin Note: I’ve written ‘mothers’ instead of ‘moms’. 'Moms' is too informal for a CV.
