Learn Swahili from English in Tanzania

I'm a professional literate teacher with a passing grade of "B" in both Kiswahili and English in my secondary school results.
I failed to go ahead with my studies because of family's economic position is very low, hence, I suggested finding the best way how to upgrade my dreams and not fail.
Apart from this, I studied a computer short- course and came up with an average of grade "A" in both programs. I thought that I could get a job through this but resulted otherwise, finally, I decided to earn through this my current job.
