Yes, you can. You certainly can.
Actually, any adult learner who knows reasonable English
can.
First of all, let us ask you one
thing: Do you think classroom instruction for a short
period of 3 or 6 months is going to make you speak
fluent English? Why, even classroom instruction for
a long period is not likely to be really
effective - as far as fluency development is
concerned. For example, take the case of most of the
post-graduates in countries where English is a second
language. By the time they get their post-graduate
degree, won't they have learnt English as a separate
subject of study in classrooms (at school and college)
for at least 9 or 10 years? That too, from about 9
or 10 different teachers? And won't they have learnt
various other subjects through English in classrooms
for at least 7 years? That too, from about 7 other
teachers? Yet, by the time they become post-graduates,
do they become fluent enough to speak English spontaneously?
So don't be under the impression
that classroom instruction is a sure cure for all
your fluency problems - even if it stretches over
several years. Now if classroom instruction (in English
and through English) for a long period of 7
or 10 years cannot produce true fluency in you, do
you think classroom instruction for a short period
of 3 or 6 months is going to make you fluent?
Of course, classroom sessions
can do one thing that a self-study course cannot:
Classroom sessions can set up mock conversational
situations and get you to take part in them. But understand
one thing here and now: As far as fluency development
is concerned, such mock conversational situations
don't have much real value. No, they don't.
In fact, they can even have a bad effect on
your fluency development efforts. Yes, they can. (Read
on, and you'll understand). So what the Fluentzy
system gets you to do is this: It gets you to follow
the self-study route — that is, to do a self study
course using the Fluentzy books. And this process
of doing a self-study course helps you to gain the
fluency-relevant experience you need — from real-life
situations. (Now go through the answer
to Q8 thoroughly).
