Wrong tense: it was 4 years ago. The OP, predictably enough for someone who was planning to start trading with $3,000 and no experience or knowledge, by taking an "Online Trading Academy" course, made that one post only and then disappeared. His profile is "no longer available".
$3000 is enough as long as you have required skills... it has to be minimum 1 year with demo, and this is also a good time to study the price action and other technical tools; then followed by real account - with which you will find out the difference between real and demo - and the difference involves the psychological issues as well as the marginal calls; then followed by incorporating the risk management as well as diversification (into your strategy) - the knowledge you presumably have learned from the finance papers at your University . then I guess the $3000 is enough
Well as a rule of thumb you can set 1% of profit/loss from your deposit it is $30 per trade. Appropriate lot size for this bet is 0.1 lot (30 pips per trade-spread).
My guess is that you prone to lose much more in a trade than you're able to make in a month. Impressive, Isn't it ?
Yes. IMHO most losers are fragile. Which is a left (Negative) tailed return's distribution. At best, Lots of small gains and few but fatal / enormous losses.
I think this scenario is probably much more common than many people realise. A lot of people who don't have a particularly clear understanding of statistics and probability "feel safer" having a high win-rate, and are willing, during their self-education process, only to conceptualise their aspirations in terms of methods with high win-rates. I don't suggest that it's impossible for that approach ever to work, of course, but it's clearly one which hinders many people, and it significantly limits the perspective of the picture they're looking at. Nobody was born with an understanding of probability and statistics, and some people (especially in collusion with others, for instance in places like "forums") fool themselves into believing that acquiring some understanding of it "isn't really necessary" and that its deficiency "won't really matter". For most them, of course, it will matter very much indeed. But there you go - most people don't really want to learn how to trade, even when they say they do. Most people want to have learned how to trade: they want the outcome without the process.
